4x+2y+z =6 2x+3y-z = 13/2 3x+2y+2z =7 bearapakah nilai persamaan nya ? bsk dikumpul mohon bantuannya ya

4x+2y+z=6 | x1 = 4x+2y+z=6
2x+3y-z=13/2 |x2 = 4x+6y-z=13

2y+z=6
6y-z=13
8y=19
y=19/8

2y+z=6
2.19/8 +z =6
38/8+z=6
z= 6-38/8
z=4

4x+2y+z=6
4x+2.19/8+4=6
4x+38/8+4=6
4x+42/8=6
4x=6-42/8
4x=-36/8
x=4+36/8
x=40/8
x=5
