Given :-
- Pranav ran 20.3 km more than Branda
- Pravin ran 38.6 km
[tex] \\ \\ [/tex]
To find :
- No. of kilometers did Brenda run.
[tex] \\ \\ [/tex]
Let :
- No. of kilometers ran by Brenda be x.
[tex] \\ \\ [/tex]
Solution:
[tex] \\ \\ [/tex]
Equation formed:-
[tex] \\ \\ [/tex]
Total distance covered by Pravan = More distance covered by Pravan + distance covered by Brenda.
Therefore:-
[tex] \\ \\ [/tex]
[tex] \leadsto \sf38.6 = 20.3 + x[/tex]
Write the equation
[tex] \\ \\ [/tex]
[tex] \leadsto \sf38.6 - 20.3 =x[/tex]
When we transfer 20.3 to left side the positive sign (+) will change into negative sign (–)
[tex] \\ \\ [/tex]
[tex] \leadsto \sf x = 38.6 - 20.3[/tex]
Arrange the equation because x is always represented at left side.
[tex] \\ \\ [/tex]
[tex] \leadsto \boxed {\pmb{\sf x = 18.3}}\star[/tex]
After subtracting 38.6 with 20.3 we will get result as 18.3 .

[tex] \therefore \red{ \underline{ \pmb{\frak{Distance ~ covered ~by ~Brenda~ is ~equal ~to~18.3~kilometers}}}}[/tex]
