Question

Alguém me ajuda a resolver por favor​

Answer 1

$\frac{x}{2} - y = - 24 \\ x - 2y = - 48$

$2x - \frac{y}{3} = 14 \\ 6x - y = 42$

{x-2y=–48

{6x–y=42 ×(–2)

{x–2y=–48

+ {–12x+2y=–84

–11x=–132×(–1)

$11x = 132 \\ x= \frac{132}{11} \\ x = 12$

$6x - y = 42 \\ y = 6x - 42 \\ y = 6.12 - 42 \\ x = 72 - 42 \\ x = 30$
