4y-4-\left(y-5\right)=10
Use the distributive property to multiply 4 by y-1.
4y-4-y-\left(-5\right)=10
To find the opposite of y-5, find the opposite of each term.
4y-4-y+5=10
The opposite of -5 is 5.
3y-4+5=10
Combine 4y and -y to get 3y.
3y+1=10
Add -4 and 5 to get 1.
3y=10-1
Subtract 1 from both sides.
3y=9
Subtract 1 from 10 to get 9.
y=\frac{9}{3}
Divide both sides by 3.
y=3
Divide 9 by 3 to get 3.
