Which of the following is the solution to the equation 2/3 over 3x = 12?
andrey2020 [161]

Answer:

<u>x = 54 and none of the alternatives given is correct</u>

Step-by-step explanation:

Let's solve for x in the equation given, this way:

2/3 ÷ 3x = 12

2/3 * x/3 = 12

2x/9 = 12

2x = 108

x = 108/2 = 54

Proof of x = 54

2/3 * 54/3 = 108/9 = 12

<u>x = 54 and none of the alternatives given is correct</u>
