6x - 2y + 3z=17
5x - 3y + 2z=11
2x - 9y - 4z= -16

Sagot :

6x - 2y+ 3z = 17

Solve for x  x = 17/6 + y/3 - z/2

Solve for y   y = - 17/2 + 3x+ 3z/2

Solve for z   z = 17/3 -2x +2y/3

5x - 3y - 2z = 11

Solve for x   x = 11/5 + 3y/5 + 2z/5

Solve for y   y = -11/3 + 5x/3 + 2z/3

Solve for z   z = -11/2 + 5x/2 - 3y/2

2x - 9y -4z = -16

Solve for x   x = -8 + 9y/2 + 2z

Solve for y   y = 16/9 + 2x/9 - 4z/9

Solve for z   z = 4 + x/2 -9y/4
