Solved by pluggable solver: SOLVE linear system by SUBSTITUTION

Solve:
We'll use substitution. After moving 3*y to the right, we get:
, or . Substitute that
into another equation:
and simplify: So, we know that y=2. Since , x=-3.

Answer: .

Solved by pluggable solver: Linear System solver (using determinant)

Solve:

Any system of equations:

has solution

(x=-3, y=2}

Hope this helps!
