Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++3%5Cx+%2B+2%5Cy+=+25%2C%0D%0A++++7%5Cx+%2B+4%5Cy+=+57+%29%0D%0A++We'll use substitution. After moving 2*y to the right, we get:
3%2Ax+=+25+-+2%2Ay, or x+=+25%2F3+-+2%2Ay%2F3. Substitute that
into another equation:
7%2A%2825%2F3+-+2%2Ay%2F3%29+%2B+4%5Cy+=+57 and simplify: So, we know that y=2. Since x+=+25%2F3+-+2%2Ay%2F3, x=7.

Answer: system%28+x=7%2C+y=2+%29.
