From eq. 2,
\n" ); document.write( " $\"y=7x%2B36\"$
\n" ); document.write( "Substitute into eq. 1,
\n" ); document.write( " $\"5x%2B3%287x%2B36%29=-22\"$
\n" ); document.write( " $\"5x%2B21x%2B108=-22\"$
\n" ); document.write( " $\"26x=130\"$
\n" ); document.write( " $\"highlight%28x=5%29\"$
\n" ); document.write( "Now that you have x, use either equation to solve for y. \n" ); document.write( "
