Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++1%5Cx+%2B+-1%5Cy+=+3%2C%0D%0A++++3%5Cx+%2B+-2%5Cy+=+3+%29%0D%0A++We'll use substitution. After moving -1*y to the right, we get:
1%2Ax+=+3+-+-1%2Ay, or x+=+3%2F1+-+-1%2Ay%2F1. Substitute that
into another equation:
3%2A%283%2F1+-+-1%2Ay%2F1%29+%2B+-2%5Cy+=+3 and simplify: So, we know that y=-6. Since x+=+3%2F1+-+-1%2Ay%2F1, x=-3.

Answer: system%28+x=-3%2C+y=-6+%29.
