Question

Qual o valor de X, Y e Z sabendo que:
2z × 3y = 2x

3x + z = 10

z × y = 10

Answer 1

Resposta:

Explicação passo-a-passo:

$2z.3y=2x\ (i)\\3x+z=10\ (ii)\\z.y=10\ (iii)$

De (i)

$z.y=\frac{1}{3}x$

Por (iii):

$10=\frac{1}{3}x\\=>x = 30$

De (ii)

$3(30)+z=10\\z=10-90\\z = -80$

De (iii):

$-80y=10\\\\y = -\frac{10}{80}\\\\y = -\frac{1}{8}$

Resposta:

$x=30\\\\y=-\frac{1}{8}\\\\z = -80$
