Question

4x – 22 =2
2x - y + z = 2
(x - 2y + 3z = -4​

Answer 1

Resposta:

4x - 22 = 2

4x = 2 + 22

4x = 24

x = 24/4

x = 6

2x - y + z = 2

2(6) - y + z = 2

12 - y + z = 2

-y + z = 2 - 12

-y + z = -10

z = -10 + y

x - 2y + 3z = -4

6 - 2y + 3(-10 + y) = -4

6 - 2y - 30 + 3y = -4

y = -4 + 24

y = 20

z = -10 + y

z = -10 + 20

z = 10

S = {6, 20, 10}
