5x-2x+10=7x-2
Use the distributive property to multiply -2 by x-5.
3x+10=7x-2
Combine 5x and -2x to get 3x.
3x+10-7x=-2
Subtract 7x from both sides.
-4x+10=-2
Combine 3x and -7x to get -4x.
-4x=-2-10
Subtract 10 from both sides.
-4x=-12
Subtract 10 from -2 to get -12.
x=\frac{-12}{-4}
Divide both sides by -4.
x=3
Divide -12 by -4 to get 3.
