Multiply the first equation by $\"240\"$ ,
\n" ); document.write( " $\"15x%2B16y=108\"$
\n" ); document.write( "Multiply the second equation by $\"540\"$ ,
\n" ); document.write( " $\"27x-20y=48\"$
\n" ); document.write( "Multiply the first equation by 5 and the second equation by 4 and add them,
\n" ); document.write( " $\"75x%2B80y%2B108x-80y=540%2B192\"$
\n" ); document.write( " $\"183x=732\"$
\n" ); document.write( " $\"x=4\"$
\n" ); document.write( "Then use either equation to solve for $\"y\"$ .
\n" ); document.write( " $\"60%2B16y=108\"$
\n" ); document.write( " $\"16y=48%7D%7D%0D%0A%7B%7B%7By=3\"$
