You can put this solution on YOUR website!
4X+7Y=-14 MULTIPY THIS EQUATION BY -5 WE GET -20X-35Y=70
\n" ); document.write( "8X+5Y=8 NOW MULTIPLY THIS EQUATION BY 7 WE GET 56X+35Y=56 NOW ADD
\n" ); document.write( "-20X-35Y=70
\n" ); document.write( "56X+35Y=56
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "36X=126
\n" ); document.write( "X=126/36
\n" ); document.write( "X=3.5 SOLUTION
