Solve the system

2x+5y=1
-x+6y=8

Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++2%5Cx+%2B+5%5Cy+=+1%2C%0D%0A++++-1%5Cx+%2B+6%5Cy+=+8+%29%0D%0A++We'll use substitution. After moving 5*y to the right, we get:
2%2Ax+=+1+-+5%2Ay, or x+=+1%2F2+-+5%2Ay%2F2. Substitute that
into another equation:
-1%2A%281%2F2+-+5%2Ay%2F2%29+%2B+6%5Cy+=+8 and simplify: So, we know that y=1. Since x+=+1%2F2+-+5%2Ay%2F2, x=-2.

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