Using SUBSTITUTION, the following will solve the system of equations given as




Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
We'll use substitution. After moving 2*y to the right, we get:
, or . Substitute that
into another equation:
and simplify: So, we know that y=12. Since , x=-2.66666666666667.

Answer: .
