cari nilai x,y,z


mohon bantuannya teman" ​

Answer 1

Jawab:

Diketahui :

2x + 2y + 2z = 4

2y + 6z = 10

8z = 16

Ditanya : x,y,z?

Jawab :

8z = 16

z = 16/2

z = 8

2y + 6z = 10

2y + 6(8) = 10

2y + 48 = 10

2y = 10 - 48

2y = - 38

y = -38/2

y = -19

2x + 2y + 2z = 4

2x + 2(-19) + 2(8) = 4

2x + (-38) + 16 = 4

2x - 22 = 4

2x = 4 + 22

2x = 26

x = 13

Semangat belajar! ^_^
