when 28 chocolates are added to x amount of   sweets and the total is tripled, the answer is 5 times the original number.
solution:
number of chocolates= 28
added to x= 28 + x
total is halved= 28+ x/3
answer is 5 times ori. no.= 28+x/3=5x
28+x=15x
x-15x=-28
-14x=-28

Algebraic Equation Q:
When a number is added to 8 result is equal to subtracting 16 from three times of it.
What is the number.

* Let the number be X
*Added to 8: 8+X
* result is equal to subtracting 16 from three times of it:8+X=16-3X

8+X=3X-16
8+16=-X+3x
24=-2X
24/2=X
12=X
X=12

Algebraic Fractional EquationQ: Faraz and Hamza divided $44 into 2 shares. 2/4 of Faraz’s share is equal to 3/5 of Hamza’s share. How much does each get?

# data[].attributes.body
Ans: Total Amount= $44
Faraz's share= 2/4 of 44
Hamza's share= 3/5 of 44
Let the shared amount be = x

2/4x = 3/5(44-x)
10x=12(44-x)

10x= 528 - 12x                Variables at one side
10x+12x= 528
22x= 528
x= 528/22
x= 24

Share No.1 = 24
Share No.2= 44-24= 20

Umer is 4 times older than Umar. After 15 years Umer will be 4 times old as he is now. How old is Umar?

SOLUTION:
Let Umar's age be x
4 times of his age = 4x
In 15 years time Umer's age = (x+15)=4x
(x+15)-4x=0
x-4x+15=0
-3x=0-15
-3x=-15
x=-15/-3
x=5
Umer's age: 5x4=20

Sahar Hasan and Maryam Asad.

When a number is divided by 2 and has 22 added to it. The result is added by 5. Find the number…….
Solution

X + 22 = x + 5

2
X  = x + 5 – 22

2

X   = x – 17

2

X = 2 (x – 17)

X = 2x – 34

X – 2x = - 34
-x = - 34

X = 34
