Multiply the second equation by 2 and add the equations together.

\n" ); document.write( " $\"-5x=-25\"$
\n" ); document.write( " $\"x=5\"$
\n" ); document.write( "Then use either equation to solve for $\"y\"$ .
\n" ); document.write( " $\"-5-y=-2\"$
\n" ); document.write( " $\"y=-5%2B2\"$
\n" ); document.write( " $\"y=-3\"$
\n" ); document.write( " \n" ); document.write( "
