Question

Alguém sabe me responde a c?​

Answer 1

Resposta:

$x=\frac{7}{2},y=6$

Explicação passo-a-passo:

$2x + y=13,4x+3y=32\\\\\\2x+y=13\\2x=-y+13\\\\x=\frac{1}{2} (-y +13)\\x=\frac{1}{2}y + \frac{13}{2} \\\\4 (-\frac{1}{2} + \frac{13}{2} )+3y=32\\-2y+26+3y=32\\y+26=32\\y=6\\x=-\frac{1}{2} x 6 +\frac{13}{2} \\x=-3+\frac{13}{2} \\x=\frac{7}{2}$
