You can put this solution on YOUR website!
Subtract the equations to cancel out x and solve for y
\n" ); document.write( "x - 2y = 8
\n" ); document.write( "x + y = 2
\n" ); document.write( "...
\n" ); document.write( "x - x - 2y - y = 8 - 2
\n" ); document.write( "-3y = 6
\n" ); document.write( "y = -2
\n" ); document.write( "...
\n" ); document.write( "Multiply the second equation by 2 and add to the first equation
\n" ); document.write( "x-2y=8
\n" ); document.write( "2x+2y=4
\n" ); document.write( "x + 2x - 2y + 2y = 8 + 4
\n" ); document.write( "3x = 12
\n" ); document.write( "x = 4
\n" ); document.write( "...
