\n" ); document.write( "Simply plug in x=2 and y = -3 into 4x+5y=-7 and simplify. If the two sides of the equation are equal, then the ordered pair (2, -3) is a solution. \r
\n" ); document.write( "\n" ); document.write( "I still am not understanding how the problem is done. I'm really lost!
\n" ); document.write( "x=2+5=7 not -7 and y=-3+4=1 so how does that makes the equation equal? or do you make it x=-2 + -5=-7 and y=-3 + -4=-7?
