Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++6%5Cx+%2B+-1%5Cy+=+18%2C%0D%0A++++8%5Cx+%2B+1%5Cy+=+24+%29%0D%0A++We'll use substitution. After moving -1*y to the right, we get:
6%2Ax+=+18+-+-1%2Ay, or x+=+18%2F6+-+-1%2Ay%2F6. Substitute that
into another equation:
8%2A%2818%2F6+-+-1%2Ay%2F6%29+%2B+1%5Cy+=+24 and simplify: So, we know that y=0. Since x+=+18%2F6+-+-1%2Ay%2F6, x=3.

Answer: system%28+x=3%2C+y=0+%29.
