To solve the given equation, w need to review some rules:

The given equation is :


⇒⇒⇒⇒ rule (2)

⇒⇒⇒⇒ rule (1) and rule (2)

⇒⇒⇒⇒ rule (3)
removing the nature logarithm from both sides

∴ x = 4
So, the correct answer is option (2) ⇒⇒⇒⇒ x = 4

Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
To find the x-coordinate, substitute y = 8 into the equation abd solve for x
5x - 7 = 8 ( add 7 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
Thus (3, 7) is a solution to the equation
