$\"2x%2B5y=1\"$
\n" ); document.write( " $\"3x%2B2y=7\"$
\n" ); document.write( "Multiply the first equation by 2 and the second by 5 and subtract them to eliminate x.
\n" ); document.write( " $\"4x%2B10y-%2815x%2B10y%29=2-35\"$
\n" ); document.write( " $\"4x-15x%2B10y-10y=-33\"$
\n" ); document.write( " $\"-11x=-33\"$
\n" ); document.write( " $\"x=3\"$
\n" ); document.write( "Now use either equation to solve for y.\r
