You can put this solution on YOUR website!
Because y=-4, you can substitute -4 for y in the second equation:
\n" ); document.write( " $\"-3x-6%28-4%29=15+=-3x-6y\"$
\n" ); document.write( "Multiply
\n" ); document.write( " $\"-3x%2B24=15\"$
\n" ); document.write( "Subtract 24 from both sides
\n" ); document.write( " $\"-3x=-9\"$
\n" ); document.write( "Divide both sides by -3
\n" ); document.write( " $\"x=3\"$
\n" ); document.write( "

x=3

\n" ); document.write( "
