Question

Solve for x. 7(x - 3) = 4(x 5) x = x = x = x = user: which of the following is the solution set of the given equation? (x - 3) - 2(x 6) = -5 {-10} {-4} {8}

Answer 1

7(x - 3) = 4(x + 5)
7x - 21 = 4x + 20
7x - 4x = 20 + 21
3x = 41
x = 41/3

(x - 3) - 2(x + 6) = -5
x - 3 - 2x - 12 = -5
-3x - 15 = -5
-3x = -5 + 15
-3x = 10
x = -10/3
