Find the ordered pair which is a solution of the equation 2x - y = 9?

Solution:

Given equation 2x - y = 9

Here, the unknown variables are x, y

Since there are two unknowns in the given equation we need two sets of equations to solve

As we are not given the second set of equations, we cannot solve

There can be any value of x which can give the value 9 such as (x, y) = (9/2, 0)

Hence, there are infinitely many solutions for the given equation which among them (9/2, 0) can be one solution.

Find the ordered pair which is a solution of the equation 2x - y = 9?

Summary:

The ordered pair of which can be one of the infinite solutions of equation 2x - y = 9 is (9/2, 0).
