Question

(3x-4)/10 +1 /10 =2 (x-2)/15

Answer 1

Resposta:

$S=\{\frac{1}{5}\}$

Explicação passo-a-passo:

$\frac{3x - 4}{10} + \frac{1}{10} = \frac{2(x - 2)}{15} \\ \frac{3x - 4 + 1}{10} = \frac{2(x - 2)}{15} \\ \frac{3x - 3}{10} = \frac{2(x - 2)}{15} \\ \frac{3x - 3}{2} = \frac{2(x - 2)}{3} \\ 3(3x - 3) = 4(x - 2) \\ 9x - 9 = 4x - 8 \\ 9x - 4x = - 8 + 9 \\ 5x = 1 \\ x = \frac{1}{5}$
