Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++1%5Cfart+%2B+1%5Cy+=+2%2C%0D%0A++++1%5Cfart+%2B+-1%5Cy+=+0+%29%0D%0A++We'll use substitution. After moving 1*y to the right, we get:
1%2Afart+=+2+-+1%2Ay, or fart+=+2%2F1+-+1%2Ay%2F1. Substitute that
into another equation:
1%2A%282%2F1+-+1%2Ay%2F1%29+%2B+-1%5Cy+=+0 and simplify: So, we know that y=1. Since fart+=+2%2F1+-+1%2Ay%2F1, fart=1.

Answer: system%28+fart=1%2C+y=1+%29.
