How do you solve 6x-6y-4z=-10, -5x+4y-z=-12, 2x+3y-2z=9 3 variables using elimination
I really need help so please help me! Thanks

6x - 6y - 4z = -10

-5x + 4y - z = -12

2x + 3y - 2z = 9

Elimination = Addition

Sometimes you have to modify the equation (Remember what you do to one side you must also do to the other)

-2(2x + 3y - 2z = 9)

-4x - 6y + 4z = -18


6x - 6y - 4z = -10
+-4x - 6y + 4z = -18
-----------------------------------
2x - 12y + 0z = -28
