Question:
Complete the following activity to solve the simultaneous equations.
5x + 3y = 9 -----(I)
2x + 3y = 12 -----(II)
Step-by-step explanation:
5x + 3y = 9 -----(I)
2x + 3y = 12 -----(II)
Add (I) & (II)
7x = 21
x = 3
Putting the value of x = 3 in (I) we get
5(3) + 3y = 9
⇒ 15 + 3y = 9
⇒ 3y = 9 - 15 = - 6
⇒ y = - 2
Thus,
(x, y) = (3, -2)
