You can put this solution on YOUR website!
y=2x+1
\n" ); document.write( "x+y=4 [Pick either equation and solve for one of the variables]
\n" ); document.write( "x+y=4
\n" ); document.write( "y=-x+4 [Plug the value of (y=-x+4) into the first equation and solve for x]
\n" ); document.write( ".
\n" ); document.write( "y=2x+1
\n" ); document.write( "-x+4=2x+1 [solve for x]
\n" ); document.write( "4=3x+1
\n" ); document.write( "3=3x
\n" ); document.write( "x=1 [Plug (x=1) back into either equation and solve for y]
\n" ); document.write( ".
\n" ); document.write( "x+y=4
\n" ); document.write( "1+y=4 [Solve for y]
\n" ); document.write( "y=3
\n" ); document.write( ".
\n" ); document.write( "Check by plugging the values of x and y back into either equation.
\n" ); document.write( "y=2x+1
\n" ); document.write( "3=2(1)+1
\n" ); document.write( "3=2+1
\n" ); document.write( "3=3 [Checks out]
\n" ); document.write( " \n" ); document.write( "
\n" );
