What is the ordered pair of the solution -4x plus 8y equals 40 and -2x-2y equals 2?
[x = -4, y = 3]. There is more than 1 way to solve. Here's one:
- multiply second equation by 4: -8x - 8y = 8
- add to first equation {eliminating y}: -12x = 48
- divide this by -12: x = -4.
Now substitute x = -4 into either of the original equations:
- -2(-4) - 2y = 2
- 8 - 2y = 2 ---> -2y = -6 ---> y = 3.
Check in the other equation: -4(-4) + 8(3) = 16 + 24 = 40 [checks out]

What is the ordered pair to 2x-5y equals -1?
The equation 2x-5y=-1 has a graph that is a line. Every point on that line is an ordered pair that is a solution to the equation. So pick any real number x and plug it in. You will find a y and that pair (x,y) is an ordered pair that is a solution to this equation. For example, let x=0 Then we have -5y=-1so y=1/5 The ordered pair (0, 1/5) is a point on the line and a solution to the equation.
