Explanation: 

(a) Given that |𝑥+1|+(𝑦+2)^2 = 0

Sum of an absolute value & a perfect square value can be equal to 0 only when each of these terms is equal to 0.

∴ |𝑥+1| = 0

⇒ 𝑥 = −1 & (𝑦+2)^2 = 0 ⇒ y + 2 = 0 ⇒ y = −2

Putting the values of x and y in the equation,ax−3ay = 1,

we get a (-1)- 3a (-2) = 1

⇒ -a + 6 a = 1

⇒ a = 1 5 Ans.
