Okay,
\n" ); document.write( " $\"5x%2B3y=-13\"$ -------------> eqn 1
\n" ); document.write( " $\"7x-2y=19\"$ --------------> eqn 2
\n" ); document.write( "In eqn 1 we get,
\n" ); document.write( " $\"y=%28-13-5x%29%2F3\"$ -----------> eqn 3
\n" ); document.write( "Substitute eqn 3 in eqn 2,
\n" ); document.write( " $\"7x-2%28%28-13-5x%29%2F3%29=19\"$
\n" ); document.write( " $\"7x%2B%2826%2B10x%29%2F3=19\"$
\n" ); document.write( " $\"%2821x%2B26%2B10x%29%2F3=19\"$ ---------> $\"31x%2B26=19%2A3\"$
\n" ); document.write( " $\"31x=57-26\"$ -----------> $\"cross%2831%29x%2Fcross%2831%29=cross%2831%29%2Fcross%2831%29\"$
\n" ); document.write( " $\"x=1\"$
\n" ); document.write( ".
\n" ); document.write( "For \"y\" go back eqn 3, $\"y=%28-13-5%2A1%29%2F3\"$
\n" ); document.write( " $\"y=-6\"$
\n" ); document.write( "See graph below for your reference.
