u should post in AskQ. Why use algebra? Model is easier for kids.
Let x be no of sweets given to S by J
120  x  40 = 48 + x
2x = 32
x = 16
OR
(120  x)  (48 + 4) = 40
2x = 72  40
x = 16

Hi, Thanks thanks.
Modelling is hard to understand so hard to explain.

I think the more important question is whether your child prefers model or algebra.
