Multiply the first equation by 2 and subtract from the second.

\n" ); document.write( " $\"-6y=-18\"$
\n" ); document.write( " $\"y=3\"$
\n" ); document.write( "Then use either equation to solve for $\"x\"$
\n" ); document.write( " $\"2x%2B12=8\"$
\n" ); document.write( " $\"2x=-4\"$
\n" ); document.write( " $\"x=-2\"$ \r
