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