4y+12=5\left(y+4\right)
Use the distributive property to multiply 4 by y+3.
4y+12=5y+20
Use the distributive property to multiply 5 by y+4.
4y+12-5y=20
Subtract 5y from both sides.
-y+12=20
Combine 4y and -5y to get -y.
-y=20-12
Subtract 12 from both sides.
-y=8
Subtract 12 from 20 to get 8.
y=-8
Multiply both sides by -1.
