Answer:

Yes

Step-by-step explanation:

If it is a solution to these equations, it must satisfy them for x = 2 and y = 7.

(i) 3(2) - 2(7) should be equal to -8.

⇒ 6 - 14

⇒ - 8

  Hence, 3x - 2y = -8,   for x = 2 and y = 7

(2, 7) is a solution to 3x - 2y = -8.

(ii): 3(2) + 2(7) should be equal to 20

⇒ 6 + 14

⇒ 20

    Hence, 3x + 2y = 20,   for x = 2 and y = 7

(2, 7) is a solution to 3x + 2y = 20.

Therefore, (2, 7) is a solution to both the equations.
