You can put this solution on YOUR website!
hi,\r
\n" ); document.write( "\n" ); document.write( "i have done so many simultaneous equation solutions on here...have a look at those. Remember, you need to add or subtract the 2 equations together to remove one of the unknowns. Once don, you can find te remaining unknown.\r
\n" ); document.write( "\n" ); document.write( "If you never know whether to add or substract the equations, look at the signs of the letter you are trying to remove:\r
\n" ); document.write( "\n" ); document.write( "if the signs are the Same then Subtract...SSSSSSSSSSSSS Subtract
\n" ); document.write( "if the signs are Different then aDD...DDDDDDDDDDDD Add :-D\r
\n" ); document.write( "\n" ); document.write( "go and try\r
