Question

como resolver? 3(x-1/5)+2x/3<8​

Answer 1

Resposta:

$x < \frac{129}{19}$

Explicação passo-a-passo:

$3( \frac{x - 1}{5} ) + \frac{2x}{3} < 8 \\ \frac{3x - 3}{5} + \frac{2x}{3} < 8 \\ \frac{3(3x - 3) + 10x}{15} < \frac{120}{15} \\ 3(3x - 3) + 10x < 120 \\ 9x - 9 + 10x < 120 \\ 9x + 10x < 120 + 9 \\ 19x < 129 \\ x < \frac{129}{19}$
