Question

1. The students of class 6 of a school planted saplings around the school to reduce air pollution. The class has threesections. The students of section A planted 18 saplings and those of section C planted 13 saplings. Assume that the students of section B planted x saplings. Write an algebraic expression for the total number of saplings planted by the students of class 6.

Answer 1

your answer:--------------------
18+13+x=31+x

Answer 2

$\mathsf{\underline{ \ Given \ : \ }}$

$\mathsf{Saplings \ planted \ by \ section \ A \ = \ 18}$

$\mathsf{Saplings\ planted \ by \ section \ C \ = \ 13}$

$\mathsf{Saplings \ planted \ by \ section \ B \ = \ x}$



$\mathsf{\underline{ \ Solution \ : \ }}$

$\mathsf{Total \ saplings \ = \ 18 + 13 + x \ = \ 31 + x}$

$\therefore$

${\boxed{\boxed{\boxed{\mathsf{\red{\underline{Algebraic \ expression \ = \ 31 + x}}}}}}}$
