Answer 1

Answer:

☺☺☺

Step-by-step explanation:

Multiply both sides of the equation by 21.

23x - 1 + 10 = 278

Subtract 10 on both sides of the equation.

23x - 1 = 268

Log both sides of the equation and bring all exponents as the coefficient of logs.

(3x - 1)Log(2) = Log(268)

3x - 1 = Log(268) / Log(2)

3x = [Log(268) / Log(2)] + 1

x = (1/3) * [(Log(268) / Log(2)) + 1]
