Ajuda-meee alguém???​

Answer 1

Resposta:

$a) \frac{x}{2} + 5 = - 1 \\ \frac{x}{2} = - 1 - 5 \\ \frac{x}{2} = - 6 \\ x = - 6 \times 2 \\ x = - 12 \\ b) \frac{x}{3} - 4 = 0 \\ \frac{x}{4} = 4 \\ x = 4 \times 4 \\ x = 16 \\ c) \frac{x}{4} + 10 = - 10 \\ \frac{x}{4 } = - 10 - 10 \\ \frac{x}{4} = - 20 \\ x = - 20 \times 4 \\ x = - 80 \\ d) \frac{y}{5} - 5 = 5 \\ \frac{y}{5} = 5 + 5 \\ \frac{y}{5} = 10 \\ y = 10 \times 5 \\ y = 50$
