Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++1%5Cx+%2B+-6%5Cy+=+13%2C%0D%0A++++-6%5Cx+%2B+-7%5Cy+=+51+%29%0D%0A++We'll use substitution. After moving -6*y to the right, we get:
1%2Ax+=+13+-+-6%2Ay, or x+=+13%2F1+-+-6%2Ay%2F1. Substitute that
into another equation:
-6%2A%2813%2F1+-+-6%2Ay%2F1%29+%2B+-7%5Cy+=+51 and simplify: So, we know that y=-3. Since x+=+13%2F1+-+-6%2Ay%2F1, x=-5.

Answer: system%28+x=-5%2C+y=-3+%29.
