Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++1%5Cx+%2B+1%5Cy+=+-1%2C%0D%0A++++3%5Cx+%2B+3%5Cy+=+4+%29%0D%0A++We'll use substitution. After moving 1*y to the right, we get:
1%2Ax+=+-1+-+1%2Ay, or x+=+-1%2F1+-+1%2Ay%2F1. Substitute that
into another equation:
3%2A%28-1%2F1+-+1%2Ay%2F1%29+%2B+3%5Cy+=+4 and simplify: So, we know that y=-7=0. Since x+=+-1%2F1+-+1%2Ay%2F1, x=6.

Answer: system%28+x=6%2C+y=-7=0+%29.

Ignore where it says -7=0, ignore the 0 part.
