Answer 2

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

Answer 3

you could multiply the last equation by 2 and then add it to either the first or second equations. that would eliminate z.
