50 = 4(x - 7) - 6(3x - 6)
Apply the Distributive Property to get rid of the parentheses first. The Distributive Property: a(b + c) = ab + ac.
50 = 4(x - 7) - 6(3x - 6)
50 = 4x - 28 - 18x + 36
Collect like terms (constants and x-terms).
50 = 4x - 28 - 18x + 36
50 = -14x + 8
Subtract 8 from both sides to isolate the variable term.
42 = -14x
Divide both sides by -14 to isolate x.
42/-14 = -14x/-14
-3 = x
Answer:
x = -3
