Question

1/2x+2 (x+1)=1/5x+4+x+11

Answer 1

Resposta:

x = 10

Explicação passo-a-passo:

$\frac{1}{2} x + 2(x + 1) = \frac{1}{5} x + 4 + x + 11 \\ \\ \frac{x}{2} + 2x + 2 = \frac{x}{5} + 4 + x + 11 \\ \\ \frac{x}{2} + 2x - \frac{x}{5} - x = 4 + 11 - 2 \\ \\ \frac{x}{2} - \frac{x}{5} + x = 13 \\ \\ \frac{5x - 2x + 10x}{10} = 13 \\ \\ 13x = 13 \times 10 \\ 13x = 130 \\ x = \frac{130}{13} \\ \\ x = 10$
