You can put this solution on YOUR website!
3x + 5y = -16 (equation1)
\n" ); document.write( "3x-2y = -9 (equation2) \r
\n" ); document.write( "\n" ); document.write( "(Equation 1 - Equation2) \r
\n" ); document.write( "\n" ); document.write( "7y = -7
\n" ); document.write( "(Divide by 7 for both sides)
\n" ); document.write( "y= -1 \r
\n" ); document.write( "\n" ); document.write( "Sub y=-1 into equation 1
\n" ); document.write( "3x + 5(-1) = -16
\n" ); document.write( "3x -5 = -16
\n" ); document.write( "(Subract 5 from both sides)
\n" ); document.write( "3x = -11
\n" ); document.write( "x = -11/3 \r
\n" ); document.write( "\n" ); document.write( "therefore x= -11/3 and y=-1
\n" ); document.write( " \n" ); document.write( "
\n" );
