x+=+y%2F3+%2B+2
x+-+y%2F3+=+2

Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++1%5Cx+%2B+-0.333333333333333%5Cy+=+2%2C%0D%0A++++-2%5Cx+%2B+-1%5Cy+=+1+%29%0D%0A++We'll use substitution. After moving -0.333333333333333*y to the right, we get:
1%2Ax+=+2+-+-0.333333333333333%2Ay, or x+=+2%2F1+-+-0.333333333333333%2Ay%2F1. Substitute that
into another equation:
-2%2A%282%2F1+-+-0.333333333333333%2Ay%2F1%29+%2B+-1%5Cy+=+1 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.
