Answer:
syd is 23 and dev is 69
Step-by-step explanation:
Let Dev's age be x and Syd's age be y
Since Dev is 3 times older than Syd, we may write
x
=
3
y
Since the sum of their ages is 92, we may write
x
+
y
=
92
Now replacing x with 3y, we get :
3
y
+
y
=
92
Hence
y
=
92
4
=
23
and so Syd is 23 year old.
Back substituting we get Dev is 69 years old.
Nahhhh
So basically WHERE DID THE x COME FROM anyway ???
5 * 7 = 35
but
IT DOES NOT EQUAL TO
57x
It might be true depending on what the x value is, but you dont know what the x value is so ...
They will never intersect nor be parallel.
Is this what you are asking? If they will always, sometimes, or never intersect?
