me ajudem pporfavo

Answer 1

Resposta:

S = {59/4}

Explicação:

$\frac{x + 3}{2} + \frac{x + 4}{4} + \frac{x - 5}{4} = 16 \\ \frac{2(x + 3) + x + 4 + x - 5}{4} = \frac{64}{4} \\ 2(x + 3) + x + 4 + x - 5 = 64 \\ 2x + 6 + x + 4 + x - 5 = 64 \\ 2x + x + x = 64 - 6 - 4 + 5 \\ 4x = 59 \\ x = \frac{59}{4}$
