Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
\n" ); document.write( " \"+system%28+%0D%0A++++1%5Cx+%2B+3%5Cy+=+2%2C%0D%0A++++-1%5Cx+%2B+1%5Cy+=+1+%29%0D%0A++\"We'll use substitution. After moving 3*y to the right, we get:
\n" ); document.write( " \"1%2Ax+=+2+-+3%2Ay\", or \"x+=+2%2F1+-+3%2Ay%2F1\". Substitute that
\n" ); document.write( " into another equation:
\n" ); document.write( " \"-1%2A%282%2F1+-+3%2Ay%2F1%29+%2B+1%5Cy+=+1\" and simplify: So, we know that y=0.75. Since \"x+=+2%2F1+-+3%2Ay%2F1\", x=-0.25.
\n" ); document.write( "
\n" ); document.write( " Answer: \"system%28+x=-0.25%2C+y=0.75+%29\".
