Answer 2

ANSWER = 5

$\huge\mathfrak\blue{Solution}$

LHS

$\implies \: (\frac{ - 3}{11}) \: ^{x + 5} \div ( \frac{ - 3}{11} ) ^{ - 2x + 3}$

$\implies \frac{ - 3}{11} ^{(x + 5 + 2x - 3)}$

$\implies \frac{ - 3}{11} ^{( 3x + 2)}$

$\implies \frac{3}{11} ^{(3x +2)}$

RHS

$\implies \frac{ - 3}{11} ^{(2x - 5)} \times \frac{ - 3}{11}^{( - 2x - 8)}$

$\implies \frac{ - 3}{11} ^{(2x - 5 - 2x - 8)}$

$\implies \frac{ - 3}{11} ^{ (- 13)}$

since LHS = RHS ,

$\implies \frac{ - 3}{11} ^{(3x +2)} = \frac{ - 3}{11} ^{ - 13}$

Since the bases are equal ,

$\implies 3x +2 = - 13$

$\implies x = \frac{-15}{3}$

$\implies \: x= - 5$
