\"Stack\" and reduce
\n" ); document.write( "1) $\"x%2B3y=6\"$
\n" ); document.write( "2) $\"4x-5y=7\"$
\n" ); document.write( "make both have the same # of X's or Y's. Since it's easier w/ X, multiply #1 by 4
\n" ); document.write( "1) $\"4x%2B12y=24\"$
\n" ); document.write( "2) $\"4x-5y=7\"$
\n" ); document.write( "Subtract #2 from #1, don't forget the 5y is negative (-- = +)
\n" ); document.write( " $\"17y=17\"$
\n" ); document.write( " $\"y=1\"$
\n" ); document.write( ".
\n" ); document.write( "Therefore
\n" ); document.write( " $\"x%2B3y=6\"$
\n" ); document.write( " $\"x%2B3%281%29=6\"$
\n" ); document.write( " $\"x%2B3=6\"$
