How do I solve by substitution of linear equation?

The following steps will solve the system of linear equations by substitution:

Solved by pluggable solver: SOLVE linear system by SUBSTITUTION

Solve:
We'll use substitution. After moving -1*y to the right, we get:
, or . Substitute that
into another equation:
and simplify: So, we know that y=3. Since , x=5.

Answer: .

The solutions are x=5 and y=3 or the point(5,3)

I hope the above steps were helpful.
