To solve the equation 3x = 12, we need to isolate x.
Dividing both sides of the equation by 3, we have:
3x/3 = 12/3
x = 4
So, the solution to the equation is x = 4.
Therefore, the correct answer is A) 4.

To solve the equation (2/3)x = 8, we need to isolate x.
To isolate x, we can multiply both sides of the equation by the reciprocal of (2/3), which is (3/2):
(3/2)(2/3)x = (3/2)(8)
Simplifying, we get:
1x = 12
So, the solution to the equation (2/3)x = 8 is x = 12.
Therefore, the correct answer is B) 12.
