You can put this solution on YOUR website!
2x +y - z=4
\n" ); document.write( "3x +5y +z=16
\n" ); document.write( " x -2y -5z=3
\n" ); document.write( "-----
\n" ); document.write( "Add the 1st 2 equations --> 1 eqn in x & y
\n" ); document.write( "Multiply the 1st equation by 5, then subtract eqn 3 --> another equation in x&y.
\n" ); document.write( "---
\n" ); document.write( "Solve for x or y, the sub and find the other 2 variables.
\n" ); document.write( "================\r
\n" ); document.write( "\n" ); document.write( "x+2y+z=4
\n" ); document.write( "x+3y-2z=2
\n" ); document.write( "3x +y+2z =6
\n" ); document.write( "-----
\n" ); document.write( "Eliminate any of the 3 variables first, etc.
