Answer:
8.5 yrs
Explanation:
parent: 41 yrs
eldest son: x
Firstly, we will need to subtract 24 from 41 to get 2x the eldest son's age.
By doing that, we will have an equation that looks like this:
41-24=2x
This equation would basically get us through the whole problem.
Simplify the equation:
17=2x
x=8.5
The eldest son's age is 8.5.
Let's check our work!
8.5 x 2 = 17
17+24=41 (parent's age.)
Hope this helps :)
