Solve for x: 4x/9 = 18

Question

A. 18
B. 8
C. 4.5
D. 40.5

Answer 1

To isolate x, we can multiply both sides of the equation by 9 to get rid of the fraction:

4x/9 = 18
4x = 18 * 9
4x = 162

Now, divide both sides by 4 to solve for x:

x = 162 / 4
x = 40.5

Therefore, the solution is x = 40.5, so the correct answer is D. 40.5.
