The equation of a function is y= 2/3x + 1/3. Find
(a) the value of y when
(i) x=-3
(ii) x=1 1/2
(b) the value of x when
(i) y = 1
(ii) y= -1/6
If you have this book called “Think Mathematics” it’s on Secondary 1A page 151. Thank you.

Answer:
Given equation is 3x+ay=6 and solution x=1 and y=1
3x+ay=6
Put the value x=1 any y=1 we get
3×1+a×1=6
⇒3+a=6
⇒a=6−3
⇒a=3
