You can put this solution on YOUR website!
-2x+3y=-14
\n" ); document.write( " 2x+2y=4 solve for x and y
\n" ); document.write( "First you want o get an answer for one of the variables, so you solve one equation,
\n" ); document.write( "2x+2y=4
\n" ); document.write( "2x=4-2y
\n" ); document.write( "\"x=%284-2y%29%2F2\"
\n" ); document.write( "Now we have an answer for x(we aren't done yet, that is not the final answer for x.) So lets plug that in the equation for the x.
\n" ); document.write( "\"-2%28%284-2y%29%2F2%29%2B3y=-14\"
\n" ); document.write( "-4+2y+3y=-14
\n" ); document.write( "5y=-10
\n" ); document.write( "y=-2
\n" ); document.write( "Now you have the answer for y, lets now go back to the equation and find out what x=
\n" ); document.write( "2x+2(-2)=4
\n" ); document.write( "2x-4=4
\n" ); document.write( "2x=8
\n" ); document.write( "x=4\r
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "2(4)+2(-2)=4
\n" ); document.write( "8-4=4
\n" ); document.write( "4=4
\n" ); document.write( "Hope you understand
\n" ); document.write( "=) \n" ); document.write( "
\n" );
