Question

Find the value of r if 7pr=42

Answer 1

answer is 6/p
................

Answer 2

Answer:

$r=\frac{6}{p}$

Step-by-step explanation:

We have been given the equation $7pr=42$

We have to solve this equation for 'r'

Divide both sides by p.

$7r=\frac{42}{p}$

Now, we have 7 is in multiplication with r. So in order to get rid of 7, we will do reverse operation of multiplication which is division.

Thus, divide both sides by 7.

$r=\frac{42}{7p}$

On simplifying, we get

$r=\frac{6}{p}$

Thus, value of r is $r=\frac{6}{p}$
