Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
\n" ); document.write( " \"+system%28+%0D%0A++++5%5Cx+%2B+-3%5Cy+=+65%2C%0D%0A++++1%5Cx+%2B+2%5Cy+=+0+%29%0D%0A++\"We'll use substitution. After moving -3*y to the right, we get:
\n" ); document.write( " \"5%2Ax+=+65+-+-3%2Ay\", or \"x+=+65%2F5+-+-3%2Ay%2F5\". Substitute that
\n" ); document.write( " into another equation:
\n" ); document.write( " \"1%2A%2865%2F5+-+-3%2Ay%2F5%29+%2B+2%5Cy+=+0\" and simplify: So, we know that y=-5. Since \"x+=+65%2F5+-+-3%2Ay%2F5\", x=10.
\n" ); document.write( "
\n" ); document.write( " Answer: \"system%28+x=10%2C+y=-5+%29\".
