Question

2x +y -32= 8
5× + 2z = 6
4z= -8

Answer 1

Hola,

Comencemos con las ecuaciones que solo tienen una variable.

4z = -8
$z= \frac{-8}{4}$
z = -2

5x + 2z = 6
5x + 2(-2) = 6
5x -4 = 6
5x = 6 + 4
5x = 10
$x= \frac{10}{5}$
x = 2

2x + y - 32 = 8
2(2) + y - 32 = 8
4 + y - 32 = 8
y -28 = 8
y = 8 + 28
Y = 36
