Question

9 (elevado a 2x-1) = 27 (elevado a 5x+1)

Answer 1

$9^{2x-1} = 27^{5x+1}$
$3^{4x-2} = 3^{15x+3}$
4x-2=15x+3
-11x=5 x   (-1)
11x=-5
x= -5/11

Answer 2

$9^2^x^-^1 = 27^5^x^+^1\\\\ 3^2^(^2^x^-^1^) = 3^3^(^5^x^+^1^)\\\\ 2(2x-1) = 3(5x+1)\\\\ 4x-2 = 15x+3\\\\ 11x = -5\\\\ \boxed{x=-\frac{5}{11}}$
