5y-15-\left(y-2\right)=19
Use the distributive property to multiply 5 by y-3.
5y-15-y-\left(-2\right)=19
To find the opposite of y-2, find the opposite of each term.
5y-15-y+2=19
The opposite of -2 is 2.
4y-15+2=19
Combine 5y and -y to get 4y.
4y-13=19
Add -15 and 2 to get -13.
4y=19+13
Add 13 to both sides.
4y=32
Add 19 and 13 to get 32.
y=\frac{32}{4}
Divide both sides by 4.
y=8
Divide 32 by 4 to get 8.
