Answer,

X = -8


Explanation,

Step 1: Simplify both sides of the equation.

−3(3x − 5) = 87

(−3)(3x) + (−3)(−5) = 87 (Distribute)

−9x + 15 = 87

Step 2: Subtract 15 from both sides.

−9x + 15 − 15 = 87 − 15

−9x = 72

Step 3: Divide both sides by -9.

-9x/-9 = 72/-9

X = -8


Hope This Helps :-)
