Question

-2x-3y+z=-6
z=6
3x-y+z=13
What is the solution to the system of equations?

Answer 1

you are already given the z, so I would just plug into the remaining two equations and solve for x and y.

Answer 2

\(\color{black}{ -2x-3y+\color{red}{6}=-6 }\)
\(\color{black}{ 3x-y+\color{red}{6}=13 }\)

Answer 3

Simplify these 2 equations.
Then solve the resulting 2 equations for x and y.

Write your answer in the form (x, y, z).
