-4x+10-5x-7=4\left(x-3\right)-3\left(x+1\right)
Use the distributive property to multiply 5 by 2-x.
-9x+10-7=4\left(x-3\right)-3\left(x+1\right)
Combine -4x and -5x to get -9x.
-9x+3=4\left(x-3\right)-3\left(x+1\right)
Subtract 7 from 10 to get 3.
-9x+3=4x-12-3\left(x+1\right)
Use the distributive property to multiply 4 by x-3.
-9x+3=4x-12-3x-3
Use the distributive property to multiply -3 by x+1.
-9x+3=x-12-3
Combine 4x and -3x to get x.
-9x+3=x-15
Subtract 3 from -12 to get -15.
-9x+3-x=-15
Subtract x from both sides.
-10x+3=-15
Combine -9x and -x to get -10x.
-10x=-15-3
Subtract 3 from both sides.
-10x=-18
Subtract 3 from -15 to get -18.
x=\frac{-18}{-10}
Divide both sides by -10.
x=\frac{9}{5}
Reduce the fraction \frac{-18}{-10} to lowest terms by extracting and canceling out -2.
