\"10x%2B3y=11\"
\n" ); document.write( "\"7x%2B8y=-11\"
\n" ); document.write( "Multiply eq. 1 by 7 and eq. 2 by 10 and subtract to eliminate x.
\n" ); document.write( "\"70x%2B21y-70x-80y=77%2B110\"
\n" ); document.write( "\"-59y=187\"
\n" ); document.write( "Solve for y then use either equation to solve for x.
