Question

-3(3X-42)=2(7X-58) resposta por favor!

Answer 1

-3(3X-42)=2(7X-58)
-9X + 126 = 14X - 116
-9X - 14X = - 116 - 126
-23X = -242 (-1)
X = 242 / 23

Answer 2

$- 3(3x - 42) = 2(7x - 58) \\ - 9x + 126 = 14x - 116 \\ - 9x - 14x = - 116 - 126 \\ - 23x = - 242 \: \times ( - 1) \\ 23x = 242 \\ \boxed{x = \frac{242}{23} }$
