Question:

Complete the following activity to solve the simultaneous equations.

2x - 3y = 9   -----(I)

​2x + y = 13   -----(II)

Step-by-step explanation:

2x - 3y = 9   -----(I)

​2x + 3y = 13   -----(II)

Add (I) & (II)

4x = 22

x = 11/2

Putting the value of x = 11/2 in (I) we get

2(11/2) - 3y = 9

⇒ 11 + 3y = 9

⇒ 3y = 9 - 11 = -2

⇒ y = -2/3

Thus,

(x, y) = (11/2, -2/3)
