Question

Simplify the expression 5(p+q)-3p-2q and find its value if p= -2 and q= 8​

Answer 1

Answer:

The answer is 30

Step-by-step explanation:

Replace $p=-2$ and $q=8$ in the given expression

             $5(p+q)-3p-2q$

          $=5(-2+8)-3(-2)-2(8)\\=5(6)+6-16\\=30+6-16\\=36-16\\=30$

Answer 2

To simplify : $5 ( p + q ) -3p -2q$

Given : $p = -2$  and $q = 8$

Solution :

• To find the value of given expression  we substitute the values of $p$ and $q$ in the expression .

• Further by Simplifying the equation using arithmetic operation we find the required value .  
• $5 ( p + q ) -3p -2q$

        $= 5 ( -2 + 8 ) -3 (-2) - 2 (8 ) \\= 5 (5 ) + 6 - 16 \\= 25 + 6 -16 \\= 15$

Hence , value of  $5 ( p + q ) -3p -2q$  will be $15$ .
