The purpose of solving for y  is so that when you plug it back it, you would get 7 = 7

anonymous · Answer

7=2y-3
first i subtract 3 from 7 and 3.
then i get 4=2y.
second i multipli 2 by each side and i get 
4 times 2 equals 8 and 2 cancels out.
so i now have 8 equals y.
when i pluge that in i get 13.

add 3 instead

anonymous · Answer

ok i'll try that

anonymous · Answer

$$7=2y-3\
7+3=2y-3+3\
10=2y$$

because you have a  "- 3"   so to move/undo a minus, you have to add  :)
