Question

Given that p=3r-m, express r as the subject of the formula.

help pls​

Answer 1

$\huge \color{blue}{ \boxed{ \bf \underline\color{yellow}{r = \frac{p + m}{3} }}}$

Step-by-step explanation:

GIVEN :-

p = 3r - m

TO Find :-

r as the subject of the formula.

______________________________

SOLUTION :-

$\bf p = 3r - m$

By adding m both sides,

$\bf p + m = 3r - \cancel { m} + \cancel{m} \\ \\ \bf = > p + m = 3r$

Now,

By dividing 3 both sides, we get

$\bf \frac{p + m}{3} = \frac{ \cancel3r}{ \cancel3} \\ \\ \bf = > \frac{p + m}{3} = r \\ \\ \bf = > \red{ \boxed { \bf \orange{r = \frac{p + m}{3} }}}$

Hence,

By changing 'r' as subject of formula, we get our answer -

r = (p + m)/3
