Answer:

The linear equation satisfying the given condition is,


x=t+15

where x is Ravi's age and t is the number of years

(after 10 years (t=10) his age becomes 25)

Explanation:

Let x be Ravi's age

Now, his current age is unknown, but if you add 10 to it, then it becomes 25, so

x + 10 =25

so, his current age is x = 25 =10

x = 15

Now, we find the linear equation satisfying the given condition,

Let t be the number of years that have passed since the present time

so, if 0 years have passed, his age will be 15 years

after 1 year, his age will be 16 years

after 10 years, his age will be 25 years and so on

so


x = t + 15

this satisfies the given condition, since if we add ten years i.e t = 10,

then we get 25

The equation is:

⇨ x + 10 = 25

Work/explanation:

Here's the linear equation for Ravi's age.

Ravi's age is x.

If you add 10 to x you get x + 10.

That gives 25.

So the linear equation is x + 10 = 25.
