Question

Solve the following system of equations.

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

Answer 1

try subtracting eqn 1 by eqn 2 to eliminate z, and le the new equation will be eqn 4
then eqn 1 plus (eqn 3 multiply by 2) to eliminate z, and let this be eqn 5
then try elimination using eqns 4 and 5 to solve for x or y...

Answer 2

So would it be (-3, 5, -2)?
