(1) $\"+7x+%2B+6y+=+30+\"$
\n" ); document.write( "(2) $\"+9x+-+8y+=+15+\"$
\n" ); document.write( "Multiply both sides of (1) by
\n" ); document.write( " $\"4\"$ . Multiply both sides of (2) by
\n" ); document.write( " $\"3\"$ . Then add (1) and (2).
\n" ); document.write( "(1) $\"+28x+%2B+24y+=+120+\"$
\n" ); document.write( "(2) $\"+27x+-+24y+=+45+\"$
\n" ); document.write( " $\"+55x+=+165+\"$
\n" ); document.write( " $\"+x+=+3+\"$
\n" ); document.write( "Plug this back into (1) or (2)
