Consider the equation $3p+6=21$3p+6=21.
If we want to make $p$p the subject of the equation, what is the first step we should take?
Divide both sides by $3$3 to find the value of $p+6$p+6.
Subtract $6$6 from only the left-hand side of the equation.
Divide only the left-hand side of the equation by $3$3.
Subtract $6$6 from both sides to find the value of $3p$3p.
What is the second step we should take to make $p$p the subject?
Divide both sides by $3$3 to find the value of $p$p.
Add $6$6 to only the left-hand side of the equation.
Add $6$6 to both sides to find the value of $3p+6$3p+6.
Divide only the left-hand side of the equation by $3$3.
Apply the steps found in parts (a) and (b) to find the solution to the equation.
