-8(4 + 9x) = 7(-2 -11x)

STEP 1: Simplify both sides of the equation.
(−8)(4)+(−8)(9x)=(7)(−2)+(7)(−11x)(Distribute)−32+−72x=−14+−77x−72x−32=−77x−14

STEP 2: Add 77x to both sides.
−72x−32+77x=−77x−14+77x5x−32=−14

STEP 3: Add 32 to both sides.
5x−32+32=−14+325x=18

STEP 4: Divide both sides by 5.
5x/5 = 18/5
x = 18/5

YOUR FINAL ANSWER: x = 18/5
