x-3-6\left(x+2\right)=-40
Multiply both sides of the equation by 2.
x-3-6x-12=-40
Use the distributive property to multiply -6 by x+2.
-5x-3-12=-40
Combine x and -6x to get -5x.
-5x-15=-40
Subtract 12 from -3 to get -15.
-5x=-40+15
Add 15 to both sides.
-5x=-25
Add -40 and 15 to get -25.
x=\frac{-25}{-5}
Divide both sides by -5.
x=5
Divide -25 by -5 to get 5.
