Solve for x in the equation: log(2x – 1) + log(3) = log(x + 5)
(A)
x = -1/3
(B)
x = 1/3
(C)
x = 5/3
(D)
x = 8/5
Answer: (D)
Explanation:
Using the property of logarithms that states log(a) + log(b) = log(ab), we can simplify the equation as log(3(2x – 1)) = log(x + 5). Therefore, we have 6x – 3 = x + 5. Simplifying, we get 5x = 8, which gives us x = 8/5. Hence, the answer is D) x = 8/5.
