Question:
Complete the following activity to solve the simultaneous equations.
2x - 3y = 9 -----(I)
2x + 3y = 3 -----(II)
Step-by-step explanation:
2x - 3y = 9 -----(I)
2x + 3y = 3 -----(II)
Add (I) & (II)
4x = 12
x = 3
Putting the value of x = 3 in (I) we get
2(3) - 3y = 9
⇒ 6 + 3y = 9
⇒ 3y = 9 - 6 = 3
⇒ y = 1
Thus,
(x, y) = (3, 1)
