Question

Ordered pair for 5x - 2y = 30
(8,__)

Answer 1

(8, 5 )

Explanation:

Given

5x - 2y = 30 ← with x = 8, then substituting gives

(5 × 8) - 2y = 30

40 - 2y = 30 ( subtract 40 from both sides )

- 2y = - 10 ( divide both sides by - 2 )

y = 5

Thus the ordered pair is (8, 5 )

Answer 2

5

Explanation:

5(8) = 40

40 - 2(5) =30
