You can put this solution on YOUR website!
You know what you're doing, but you have to look it over really well...
\n" ); document.write( "Lets look at your problem:
\n" ); document.write( "3x-3x + y =3x +2 ...... the 3x should be negative because you subtracted it
\n" ); document.write( "-------------------------------------------
\n" ); document.write( "Know, lets begin:
\n" ); document.write( "3x + y = 2 original equation
\n" ); document.write( "y= -3x + 2 sub. 3x
\n" ); document.write( "-------------------------------------------
\n" ); document.write( "2x – y = 3 original equation
\n" ); document.write( "2x - (-3x + 2) = 3 substitute
\n" ); document.write( "2x + 3x - 2 = 3 distribute the negative one
\n" ); document.write( "5x = 5 simplify
\n" ); document.write( "x=1
\n" ); document.write( "-------------------------------------------
\n" ); document.write( "know, lets plug 1 for x in one of the equations
\n" ); document.write( "3x + y = 2 orginal equation
\n" ); document.write( "3 + y = 2
\n" ); document.write( "y= -1\r
\n" ); document.write( "
\n" ); document.write( "
