Question

guero ajuda com o passo a passo
$2.(2x + 1) + 3. (\frac{x}{6} + \frac{1}{2} ) = 3x + 10$
​

Answer 1

Resposta:

S = {13/3}

Explicação passo-a-passo:

$2.(2x + 1) + 3. (\frac{x}{6} + \frac{1}{2} ) = 3x + 10 \\ 4x + 2 + 3.( \frac{x + 3}{6} ) = 3x + 10 \\ 4x + 2 + \frac{x + 3}{2} = 3x + 10 \\ \frac{x + 3}{2} = 3x + 10 - 4x - 2 \\ \frac{x + 3}{2} = 8 - x \\ x + 3 = 2(8 - x) \\ x + 3 = 16 - 2x \\ x + 2x = 16 - 3 \\ 3x = 13 \\ x = \frac{13}{3}$
