Question

Solve the following system of equations.

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

Answer 1

to solve this u first pick just one of the variable to solve for. then you simplify two of the equations to solve for (let's say x) x. then insert the answer into the equation that you did not simplify then solve for x. the pick another variable and do the same thing i will be easier with just two variables
