Question

((3)³x-¹)÷9=9 solve this equation​

Answer 1

Answer:

x=1/3

Step-by-step explanation:

((3)³x-¹)÷9=9

((3)³x-¹)=9*9

((27x-¹)=81

x-¹=81/27=3

x=1/3

Answer 2

$(( {3}^{3} ) \times {x}^{ - 1} ) \div 9 = 9 \\ \: ({27 \times {x}^{ - 1} }) \div 9 = 9 \\ \frac{27}{9x} = 9 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: | {x}^{ - 1} = \frac{1}{ {x}^{1} } | \\ \\ 27 = 81x \\ x = \frac{27}{81} \\ x = \frac{1}{3}$
