They got 37 orders for frog earrings, 21 orders for mushroom earrings, and earned $324.50 in one week. They got 34 orders for frog earrings, 42 orders for mushroom earrings, and earned $389 the next week. How much do frog earrings cost, and how much do mushroom earrings cost? ]]> 2021-03-01 17:14:28 UTC https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1254326450 demetei000 https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1254391059 Find the two equations: 37x + 21y = 324.5 and 34x + 42y = 389. ]]> 2021-03-01 17:25:01 UTC https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1254391059 demetei000 https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1264582290 Subtract the first equation from the second equation. It should look like
 74x + 42y = 649
-34x - 42y = 389
And then the result should be 40x = 260.]]> 2021-03-03 16:17:57 UTC https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1264582290 demetei000 https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1264589491 Divide both sides by 40 to get the value of x, which is 6.5. ]]> 2021-03-03 16:19:09 UTC https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1264589491 demetei000 https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1264634291 Substitute 6.5 for the value of x in one of the equations. For example, the x in 37x + 21y = 324.5 will be replaced with 37(6.5) + 21y = 324.5 which is equal to 240.5 + 21y = 324.5]]> 2021-03-03 16:26:36 UTC https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1264634291 demetei000 https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1264653319 Solve for y in the equation you used to substitute 6.5 for x. For example, my equation is 240.5 a= 21y = 324.5 after substituting, so now I'm going to isolate x. Subtract the number that's being added to the variable in order to isolate it. For example, I'll subtract 240.5 from both sides to isolate 21y.]]> 2021-03-03 16:29:42 UTC https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1264653319 demetei000 https://padlet.com/demetei000/7ra6h31nu4kccxc8/wish/1264681363 After subtracting the number that's being added to the variable from both sides, divide both sides by the amount that the variable is being multiplied by. For example, my equation is now 21y = 84. To get the value of y, I have to divide both sides by 21. 21y / 21 = y and 84 / 21 = 4.

For the first equation, 37 x 6.5 = 240.5 and 21 x 4 = 84. 240.5 + 84 = 324.5, which is the sum of 37x + 21y.
