To solve the equation 54x = 90 and round the answer to four decimal places, follow these steps:

Step 1: Divide both sides of the equation by 54 to isolate x:
(54x) / 54 = 90 / 54

This simplifies to:
x = 1.6667

Step 2: Round the answer to four decimal places:
The four decimal places are after the first 4 digits after the decimal point, so the rounded answer is:
