Question 3(c)
Give first the step you will use to separate the variable and then solve the equation:
$\frac{20p}{3}=40$

Answer 1

$\frac{20p}{3}=40$
Step I : $\frac{20p}{3}\times 3=40\times 3\Rightarrow 20p=120$ [Multiplying both sides by 3]
Step II : $\frac{20p}{20}=\frac{120}{20}\Rightarrow p=6$ [Dividing both sides by 20]
