Step-by-step explanation:
There can be two situations
1. When maggie is older
The equation becomes x = y + 3
It can also be expressed as y = x - 3
2. When maggie is younger
The equation becomes y = x + 3

Answer:
The required equation is [tex]|y-x|=3[/tex]. If maggies is elder, then [tex]y_1=x-3[/tex] and if maggies is younger, then [tex]y_2=x+3[/tex].
Step-by-step explanation:
Let the x represents maggies age and y represents terrance age, make a table of possible values for x and y.
It is given that the difference between maggies age and terrance age is 3.
It means
[tex]|y-x|=3[/tex]
On simplification, we get
[tex]y-x=\pm 3[/tex]
[tex]y=x\pm 3[/tex]
Case 1: If maggies is elder.
[tex]y_1=x-3[/tex]
Case 2: If maggies is younger.
[tex]y_2=x+3[/tex]
The table of values is

0 -3 3
