Answer:
4x+12y = 4 (x+3y)
35x+50y = 5 (7x+10y)
18x+9y = 9 (2x+y)
32x+8y = 8 (4x+y)
100x+700y = 100 (x+7y)
Step-by-step explanation:
You basically have to figure out what x and y are being divided by to get the x and y on the other side and put that before the parenthesis. For example in the first question in order to get x you must divide 4x by 4 and to get 3y you must divide 12y by 4 as well.
