ASAP Please Eliminate the "z" variable in the last two equations by finding opposite coefficients and adding. What is the resulting equation?

x + 3y + 2z = -16
2x - y + 2z = -15
2x - 2y - z = 1

4x - 3y = -14
4x + y = -14
6x + 5y = 13
6x - 5y = -13

multiply second by negative one 
 x+3y+2z=-16 
 -2x+y-2z=15 
 just combine
 -x+4y=-1 
So in quick terms, 2x - 2y - z = 1 would be your answer, hope this helped
