Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++1%5Cx+%2B+-2%5Cy+=+-12%2C%0D%0A++++-4%5Cx+%2B+-1%5Cy+=+-24+%29%0D%0A++We'll use substitution. After moving -2*y to the right, we get:
1%2Ax+=+-12+-+-2%2Ay, or x+=+-12%2F1+-+-2%2Ay%2F1. Substitute that
into another equation:
-4%2A%28-12%2F1+-+-2%2Ay%2F1%29+%2B+-1%5Cy+=+-24 and simplify: So, we know that y=8. Since x+=+-12%2F1+-+-2%2Ay%2F1, x=4.

Answer: system%28+x=4%2C+y=8+%29.
