Given :-
- Pranav ran 20.3 km more than Branda

To find :
- No. of kilometers did Brenda run.

Let :
- No. of kilometers ran by Brenda be x.

Solution:

Equation formed:-

Total distance covered by Pravan = More distance covered by Pravan + distance covered by Brenda.
Therefore:-


Write the equation


When we transfer 20.3 to left side the positive sign (+) will change into negative sign (–)


Arrange the equation because x is always represented at left side.


After subtracting 38.6 with 20.3 we will get result as 18.3 .
