Question

(3x-2) /4- (- 4x) /2 = 2x - ( 7x - 2) /3

Answer 1

$\frac{3x - 2}{4} - \frac{-4x}{2} = 2x - \frac{7x - 2}{3} \: \: ( \times 12) \\ 3(3x - 2) - 6 \times (-4x) = 12 \times 2x - 4(7x - 2) \\ 9x - 6 + 24x = 24x - 28x + 8 \\ 9x + 24x - 24x + 28x = 6 + 8 \\ 37x = 14 \\ \boxed{x = \frac{14}{37}}$

Answer 2

Resposta:

14/37

Explicação passo-a-passo:

3(3x-2) + 6(4x) = 24x - 4(7x-2)

9x - 6 + 24x = 24x - 28x + 8

37x = 14

x = 14/37
