5x-15-4\left(x-1\right)=2x-3\left(x+2\right)
Use the distributive property to multiply 5 by x-3.
5x-15-4x+4=2x-3\left(x+2\right)
Use the distributive property to multiply -4 by x-1.
x-15+4=2x-3\left(x+2\right)
Combine 5x and -4x to get x.
x-11=2x-3\left(x+2\right)
Add -15 and 4 to get -11.
x-11=2x-3x-6
Use the distributive property to multiply -3 by x+2.
x-11=-x-6
Combine 2x and -3x to get -x.
x-11+x=-6
Add x to both sides.
2x-11=-6
Combine x and x to get 2x.
2x=-6+11
Add 11 to both sides.
2x=5
Add -6 and 11 to get 5.
x=\frac{5}{2}
Divide both sides by 2.
