Answer 151658 by jim_thompson5910(12456) About Me on 2009-06-28 16:21:25:
You can put this solution on YOUR website!
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.
I still am not understanding how the problem is done. I'm really lost!
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?

Question 201472: Answer 151674 by jim_thompson5910(12458) About Me on 2009-06-28 19:18:18:
You can put this solution on YOUR website!
4x + 5y = -7 Start with the given equation.

4(2) + 5(-3) = -7 Plug in x=2 and y=-3

8 -15 = -7 Multiply

-7 = -7 Subtract

Since the equation is true, this means that (2, -3) is an ordered pair
solution.
