You can put this solution on YOUR website!
So far you are doing great but you aren't finished yet. Now that you've solved both equations for y you can use the transitive property that says
\n" ); document.write( "if a=y and y=b then a=b so...
\n" ); document.write( "if \"%282%2F3%29x%2B4=y\" and \"y=x%2B5\" then\r
\n" ); document.write( "\n" ); document.write( "\"%282%2F3%29x%2B4=x%2B5\"\r
\n" ); document.write( "\n" ); document.write( "Solve for x\r
\n" ); document.write( "\n" ); document.write( "subtract 4 from both sides:------->\"%282%2F3%29x=x%2B5-4\"\r
\n" ); document.write( "\n" ); document.write( "subtract x from both sides------>\"%282%2F3%29x-x=1\"\r
\n" ); document.write( "\n" ); document.write( "simplify------------------------->\"-%281%2F3%29x=1\"\r
\n" ); document.write( "\n" ); document.write( "Multiply both sides by -3--------->\"x=-3\"\r
\n" ); document.write( "\n" ); document.write( "now substitute the -3 into one of the original equations\r
\n" ); document.write( "\n" ); document.write( "-y=-x+5
\n" ); document.write( "-y=-(-3)+5
\n" ); document.write( "-y=8
\n" ); document.write( "y=-8
\n" ); document.write( "
\n" );
