You can put this solution on YOUR website!
Y=0.5x+2
\n" ); document.write( "-y=-2x+4
\n" ); document.write( "'
\n" ); document.write( "That is three different variables.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You mean this:
\n" ); document.write( "y=0.5x+2
\n" ); document.write( "-y=-2x+4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solve the second equation for y, and then equate the two expressions of y.
\n" ); document.write( "2x-4=0.5x+2
\n" ); document.write( "Solve for x, and then use either equation to solve for y.
\n" ); document.write( "
\n" );
