Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++6%5Cx+%2B+2%5Cy+=+7%2C%0D%0A++++3%5Cx+%2B+1%5Cy+=+2+%29%0D%0A++We'll use substitution. After moving 2*y to the right, we get:
6%2Ax+=+7+-+2%2Ay, or x+=+7%2F6+-+2%2Ay%2F6. Substitute that
into another equation:
3%2A%287%2F6+-+2%2Ay%2F6%29+%2B+1%5Cy+=+2 and simplify: Error: 'Can't call method "invoke_solver" on an undefined value at /home/ichudov/project_locations/algebra.com/templates/Algebra/Solver/PerlSolver.pm line 115.
