Question

Express the following as an algebraic expression:​
(v) Sum of $p$ and $2r-s$ minus sum of $a$ and $3n+4x$

Answer 1

$\text{Sum of}p\text{and}2r-s=p+2r-s.......\left(i\right)$

$\text{Sum of}a\text{and}3n+4x=a+3n+4x.......\left(ii\right)$

Subtracting (ii) from (i)

$\Rightarrow$ $(p+2r-s)-(a+3n+4x)$

Hence, the required expression is $(p+2r-s)-(a+3n+4x)$.
