The advantage of using substitution is that it is faster than graphing and that you get the exact answer. The disadvantages of graphing are that it takes longer and you don't get the exact answer.

both: used to solve system of equations

-you need to find x and y

graphing: estimation

substitution: accurate, faster

# data[].attributes.body
The differences from the substitution and graphing is that:

Graphing you always make the equation in slope intercept form and then you plog the y intercept in the graph and then you graw the line by the slope.

The Substitution the equation should be isolated and you should replace the x value to the x in the equation or a y value in the y from the equation.

The similarities are that they both can be graphed and are all formed by equations.

The difference between graphing and substitution is that graphing is an estimation and substitution is exact. The similarities are that both are use for finding the intersection of two lines.

# data[].attributes.body
The similarities are that the in at least one equation, the variable should be alone. The difference would be that graphing takes a lot of time and the answer is estimated.

# data[].attributes.body
The similarities are that they both are used to find the number of the variable. The differences is that graphing takes longer time to find, but the substitution takes less time to solve and it is easier to do.

The difference between graphing and substitution are that if there is an equation with an isolated variable the substitituion is way more faster. In graphing it takes more time and is less accurate because graphing is based on estimation.

# data[].attributes.body
the differences are the speed of solving the problem with certain format of equations, which apply mostly to substitution, although it is easier to do while graphing. They are similar in the fact that they may both be solved changing the format of equations.

Graphing and su bstituion are very different but both of them are able to get the right answer if done correctly. If we try to solve the equation by graphing it will take more time and by substituting is way faster and easier since a variable has already been given.

# data[].attributes.body
Graphing and substitution are similar because: -Both can solve the same problems

- You need to find x and y variables

-Both give you the same answer in three different systems and solutions

Graphing and Substitution are different because:

- Graphing requires more accuracy and time.

- Substitution is faster but needs more steps.

- You can use both methods to be 100% sure of your final answer.

I personally think substitution is better because it is more accurate and many times faster.

The similarities of graphing and substitution are that both are used to find the value of a system of equation. The differences is that one requires more work than the other.

# data[].attributes.body
The differences between graphing and subsitution are that in graphing you get an estimate of the answer while in substituting you get the exact answer. Graphing is usually much more complex and should only be done when both equations are in slope intercept form. The similarities are that you can get similar answers in both.

# data[].attributes.body
The difference between graphing and substitution is that by graphing is an estimation and by substitution is exact. The similarity is that almost always you get the same answer.

# data[].attributes.body
The similarities is that -At least one of the equations in the system needs to be in slope-intercept.

-You get similar answers

The differences is that

-Substitution takes less time

-Graphing both need to be in slope-intercept

-Graphing doesn't get the exact answer, it's an estimate.

# data[].attributes.body
The similarites are:

- you get the same anwser

-they are easy

- they both use the y-intercept form for something

Differences

-one has much more work than another

-one is not as relaiable
