if 2x+y=3
\n" ); document.write( "-2x+5y=-9\r
\n" ); document.write( "\n" ); document.write( "What you do is you line them up according to terms...so with\r
\n" ); document.write( "\n" ); document.write( " 2x+ y= 3
\n" ); document.write( "-2x+5y=-9\r
\n" ); document.write( "\n" ); document.write( "whats 2x -2x...........0
\n" ); document.write( "whats y +5y...........6y
\n" ); document.write( "whats 3 -9............-6\r
\n" ); document.write( "\n" ); document.write( "So the new formulas after doing like terms is....
\n" ); document.write( "0+6y=-6
\n" ); document.write( "6y=-6\r
\n" ); document.write( "\n" ); document.write( "y= -1\r
\n" ); document.write( "\n" ); document.write( "Know plug y=-1 back into any of the 2 original equations to get x\r
\n" ); document.write( "\n" ); document.write( "2x +(-1)= 3
\n" ); document.write( "2x=4
\n" ); document.write( "
\n" ); document.write( "x=2\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
