1. $\"y=2x%2B16\"$
\n" ); document.write( "2. $\"2x-5y=-16\"$
\n" ); document.write( "Substitute eq. 1 in eq. 2,
\n" ); document.write( " $\"2x-5%282x%2B16%29=-16%7C%7C%7C%0D%0A%7B%7B%7B2x-10x-80=-16\"$
\n" ); document.write( " $\"-8x-80=-16\"$
\n" ); document.write( " $\"-8x=64\"$
\n" ); document.write( " $\"highlight%28x=-8%29\"$
\n" ); document.write( "Then use eq.1 to solve for y,
\n" ); document.write( " $\"y=2%28-8%29%2B16\"$
\n" ); document.write( " $\"y=-16%2B16\"$
\n" ); document.write( " $\"highlight%28y=0%29\"$
\n" ); document.write( " \n" ); document.write( "
