Answer 1

Let's solve your equation step-by-step.

x=−2(2x−7)−3(x−4)−40

Step 1: Simplify both sides of the equation.

x=−2(2x−7)−3(x−4)−40

x=(−2)(2x)+(−2)(−7)+(−3)(x)+(−3)(−4)+−40(Distribute)

x=−4x+14+−3x+12+−40

x=(−4x+−3x)+(14+12+−40)(Combine Like Terms)

x=−7x+−14

x=−7x−14

Step 2: Add 7x to both sides.

x+7x=−7x−14+7x

8x=−14

Step 3: Divide both sides by 8.
