Answer 2

Answer:

5,1

Step-by-step explanation:

Given Equations are:

(i) 7(y + 3) - 2(x + 2) = 14

⇒ 7y + 21 - 2x - 4 = 14

⇒ 7y - 2x = -3.

(ii) 4(y - 2) + 3(x - 3) = 2

⇒ 4y - 8 + 3x - 9 = 2

⇒ 4y + 3x = 19

On solving (i) * 4 & (ii) * 7, we get

⇒ 28y - 8x = -12

⇒ 28y + 21x = 133

   ---------------------

   29x = 145

       x = 5

Substitute x = 5 in (i), we get

⇒ 7y - 2x = -3

⇒ 7y - 10 = -3

⇒ y = 1

Therefore, the value of x and y are 5 and 1.

Hope it helps!
