Let's solve your equation step-by-step.
39−2(x−8)=56
Step 1: Simplify both sides of the equation.
39−2(x−8)=56
39+(−2)(x)+(−2)(−8)=56(Distribute)
39+−2x+16=56
(−2x)+(39+16)=56(Combine Like Terms)
−2x+55=56
−2x+55=56
Step 2: Subtract 55 from both sides.
−2x+55−55=56−55
−2x=1
Step 3: Divide both sides by -2.
