Question

2. Determine which ordered pair in the form (a, b) is a solution of the given equation.

7a – 5b = 28

(–3, –2)
(–2, –3)
(0, 4)
(4, 0)


3. Determine whether the ordered pairs in the form (x, y) are solutions of the given equation and select the correct answer.

Yes, both are solutions.
No, neither is a solution.
The first is a solution, but the second is not.
The first is not a solution, but the second is.

Answer 1

(4,0) is the correct answer
because
by putting the co ordinates in equation:
7a-5b=28
7(4)-5(0)=28
28-0=28
28=28
so it is the right answer
