Let R be Jordan
Let J be Jack
Here's what we know:
R = 2/3J - 1 (Jordan Is one one year younger than 2/3 The age of Jack.)
J = 30
.
Plug in the value to the equation
R = (2/3*30)-1
R = 20 - 1
R = 19
.
We can check this by putting it into the original equation:
Jordan (19) is one year younger than 2/3 of Jack (2/3*30).
19 = 20 - 1
Success!
