Combine like terms: -7y+12y= 5y
18+22=40
Now: 5y=40
Get y alone: 5y/5=40/5
Y=8

Answer: y=8

Step-by-step explanation:

To solve for y, you want to use algebraic properties to isolate y.

18-12y = -22-7y                 [add both sides by 7y]

18-5y=-22                          [subtract both sides by 18]

-5y=-40                              [divide both sides by -5]

y=8

Now, we know that y=8.
