Question

Solve for x in the equation 8x + 9 = 30.

a) x = 34
b) x = 8
c) x = 0
d) x = 44

Answer 1

The correct answer is x = 2.625. None of the given options (a, b, c, d) are correct.

Step-by-step explanation:

To solve for x in the equation 8x + 9 = 30, we first need to isolate x on one side of the equation. We can do this by subtracting 9 from both sides:

8x + 9 - 9 = 30 - 9

8x = 21

Next, we divide both sides of the equation by 8 to isolate x:

8x/8 = 21/8

x = 2.625

Therefore, the correct answer is x = 2.625. None of the given options (a, b, c, d) are correct.
