12-y=15

Add y to both sides to get: 12=15+y

Then -15 to both sides to get (this way you have y on one side and the numbers on one side): 12-15=y

y=-3

12 - y = 15

solution:

first we shift y on right by changing hi sign negative to positve

12 = 15 + y

then we subtracted 15 on both sides we get

12 - 15 = 15 - 15 + y 

-3 = y

y = -3 answer.
