Question

O valor de x na equacao 9x+1=1/27 e ?

Answer 1

$9x + 1 = \frac{1}{27} \\ \\ 27(9x+1) = 1 \\ \\ 243x + 27 = 1 \\ \\ 243x = 1 - 27 \\ \\ 243x = -26 \\ \\ x = - \frac{26}{243}$

Answer 2

9x + 1 =    1
                27

27(9x + 1) = 1
27.9x + 27.1 = 1
243x + 27 = 1
243x = 1 - 27
243x = - 26
x = - 26
      243
