Wale was twice as old as Ajay 10 years back. How old is Ajay today if Wale will be 40 years old 10. years hence?​
vagabundo [1.1K]

Using a system of equations, it is found that Ajay is 25 years old today.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Wale's age.
  • Variable y: Ajay's age.

Wale was twice as old as Ajay 10 years back, hence:

x - 10 = 2(y - 10)

x - 10 = 2y - 20

x = 2y - 10

Wale will be 40 years old in 10 years, hence:

x + 10 = 40

x = 40

Then, Ajay's present age is found as follows.

2y = x + 10

2y = 40 + 10

y = \frac{50}{2}

y = 25
