You can put this solution on YOUR website!
{-4+y=-19 } { 3x-y=15 }\r
\n" ); document.write( "\n" ); document.write( "To solve for x and y you will need to use substitution
\n" ); document.write( "First, solve for y in the first problem by adding 4 to both sides
\n" ); document.write( "-4+y=-19
\n" ); document.write( "y=4-19
\n" ); document.write( "y=-15\r
\n" ); document.write( "\n" ); document.write( "since y=-15, we can just substitute it in for y in the second equation
\n" ); document.write( "3x-(-15)=15
\n" ); document.write( "3x+15=15
\n" ); document.write( "3x=0
\n" ); document.write( "x=0\r
\n" ); document.write( "\n" ); document.write( "so, y=-15 and x=0 (0,-15)\r
\n" ); document.write( "\n" ); document.write( "To double check, just substitute the nubers in for the variables!
\n" ); document.write( "
\n" );
