1. $\"5x%2B5y=-11\"$
\n" ); document.write( "2. $\"7x-3y=19\"$
\n" ); document.write( "Let's get rid of y.
\n" ); document.write( "Multiply eq. 1 by 3 and eq. 2 by 5 and add them together.
\n" ); document.write( " $\"3%285x%2B5y%29%2B5%287x-3y%29=3%2A%28-11%29%2B5%2819%29\"$
\n" ); document.write( " $\"15x%2B15y%2B35x-15y=-33%2B95\"$
\n" ); document.write( " $\"50x=62\"$
\n" ); document.write( " $\"highlight%28x=62%2F50=31%2F25%29\"$
\n" ); document.write( "From 1,
\n" ); document.write( "1. $\"5x%2B5y=-11\"$
\n" ); document.write( " $\"5%2831%2F25%29%2B5y=-11\"$
\n" ); document.write( " $\"5y=-11-155%2F25\"$
\n" ); document.write( " $\"5y=-275%2F25-155%2F25\"$
\n" ); document.write( " $\"5y=-430%2F25=-86%2F5\"$

\n" ); document.write( ".
\n" ); document.write( "Let’s graph the equations to verify the solution.
\n" ); document.write( "The two lines are
\n" ); document.write( " $\"y=-%28%285x%2B11%29%29%2F5\"$
