Question

Solve for r. -pr + r = 8r - 2

Answer 1

$\large\blue{\tt Given :-}$

$\to\tt -pr + r = 8r - 2$

$\large\orange{\tt To \: Find :-}$

$\to\tt Value \: of \: \boxed{\bf r}$

$\large\red{\tt Solution :-}$

$:\implies\tt-pr + r = 8r - 2$

$:\implies\tt - pr + r - 8r = - 2$

$:\implies\tt - pr - 7r = - 2$

$:\implies\tt r (p + 7) = 2$

$:\implies\tt r = \underline{\boxed{\blue{\tt\frac{2}{p+7}}}}$

$\bf\therefore The \: value \: of \: r \: is \: \frac{2}{p+7}$

Answer 2

Answer:

• r = 2/(p + 7)

Step-by-step explanation:

Solving for r

• -pr + r = 8r - 2
• r - 8r - pr = -2
• - 7r - pr = -2
• r(p + 7) = 2
• r = 2/(p + 7)
