Solution

Given: 11m - 8 - m = 9 + m

$\Rightarrow$ 10m - 8 = 9 + m
(0.5 mark)

$\Rightarrow$ 10m - m = 9 + 8
(0.5 mark)

$\Rightarrow$ 9m = 17
(0.5 mark)

$\Rightarrow$ m = $\frac{17}{9}$

9 + m = 6 m + 8 - m

Value of m in the equation 9 + m = 6m + 8 - m is $\frac{1}{4}$

(m^{2} - 11 m - 42) \div (m + 3)

m

{(\frac{8}{11})}^{- 5} \times {(\frac{8}{11})}^{m} = {(\frac{8}{11})}^{- 2}

m = - 2,

m^{2} + 6 m .
