2x - 3y = 7
-37 + y = 7
The second equation simplifies to -2y = 7 so that y = -7/2
Substituting this value for y in the first equation gives
2x - 3*(-7/2) = 7
2x + 21/2 = 7
or 4x + 21 = 14
so that 4x = -7 and so x = -7/4
So the solution to the given question is (x, y) = (-7/4, -7/2)

The ordered pair below is a solution which equation?
I'm guessing that you're looking at an ordered pair AND a list of equations. Since I can't see either of them, my chances of matching them up are not looking too promising.
Choose the ordered pair that is a solution to the system of equations -x plus y equals 12?
-x+y=12is the equation of a line and since there are infinitely many points on the line and each point is represented by an ordered pair, we have infinitely many solutions.If we take x as 0, then y must be 12so (0,12) is one ordered pair that is a solution to the equation.Zero is often a nice number to pick since it makes the calculation a bit easier.
Which ordered pair is a solution to the equation y equals 2.5x plus 6.5?
(0, 6.5) is one option.
How can you determine if a ordered pair is a solution?
Substitute the values of the ordered pair into the relation. If the equation is valid then the ordered pair is a solution, and if not then it is not.

When is it possible for an ordered pair to be the solution of more than one equation?
Always. Every ordered pair is the solution to infinitely many equations.
What is the ordered pair for the equations y equals 2x plus 1 and y equals -x plus 4?
The ordered pair is (1, 3).
What is an ordered pair that makes all equations in a system true?
