Answer:
Jay is 35
Step-by-step explanation:
Creating an equation
Let:
- x = age of may
- y = age of john
- z = age of jay
Here, we are given that
- May is 15 so x = 15
- John is 5 years older than may or y = x + 5
- Jay is 15 years older than john or z = y + 15
Solving for the ages
Given that x = 15 , y = x + 5 and z = y = 15
We can firstly find the age of john or "y" as we are given the value of x
y = x + 5
==> plug in x = 15
y = 15 + 5
==> add 15 and 5
y = 20
So John is 20
Now that we have the value of y we can easily find Jay's age or the value of z
z = y + 15
==> y = 20
z = 20 + 15
==> add 20 and 15
z = 35
Hence, Jay is 35
