Answer 1

Resposta:

x = -16, y = -10

Explicação passo-a-passo:

$-1=-\frac{3y}{2}+x\\ 6y=3(x-4)\\\\x=\frac{3y}{2}-1\\ 6y=3x-12\\\\x=\frac{3y}{2}-\frac{2}{2}\\ 6y+12=3x\\\\x=\frac{3y-2}{2}\\ x=\frac{6y+12}{3}\\\\\frac{3y-2}{2} = \frac{6y+12}{3}\\\\(3y-2)*3 = (6y+12)*2\\\\9y-6 = 12y+24\\\\12y-9y=-6-24\\\\3y=-30\\\\y = -10$

Agora Vamos substituir -10 nas primeiras equações:

$6y=3(x-4)\\6*(-10)=3x-12\\-60=3x-12\\3x=-48\\x=-16$
