Final answer:
To solve the equation 3yx = 53 and find the value of YX, divide both sides of the equation by 3. The value of YX is 17.67.
Step-by-step explanation:
To solve the equation 3yx = 53 and find the value of YX, we can divide both sides of the equation by 3 to isolate yx.
So, yx = 53/3 = 17.67
Therefore, the value of YX is 17.67, which is option C.
