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=4. Since , x=1.

Answer: .

The solutions are x=1 and y=4 or the point(1,4)

I hope the above steps were helpful.
