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