First of all, I assume since the question involves two linear equation that you are looking for the values of x and y.

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=-6. Since , x=2.

Answer: .

In other words, in you plug in -3x for y in the equation 4x + y = 2. The answer would come up as x=2. You then have to plug in 2 for x, which will yield y = 6.
The solution is (2,-6)
