Step-by-step explanation: To solve the following equation


(1)/(4)(x-2)=3-(x+(1)/(6))

we will use a simple rule shown below


\begin{gathered} (a)/(b)+(c)/(d)=(a\cdot d+c\cdot b)/(b\cdot d) \\ or \\ (a)/(b)-(c)/(d)=(a\cdot d-c\cdot b)/(b\cdot d) \end{gathered}

Above we can see how to sum or subtract fractions.

Step 1: Let's calculate as follows


\begin{gathered} (1)/(4)(x-2)=3-(x+(1)/(6)) \\ (x)/(4)-(2)/(4)=3-x-(1)/(6) \\ (x)/(4)+x=3+(2)/(4)-(1)/(6) \\ (x+4\cdot x)/(4)=3+(6\cdot2-4\cdot1)/(4\cdot6) \\ (x+4x)/(4)=3+(8)/(24) \\ (5x)/(4)=(3\cdot24+8)/(24) \\ (5x)/(4)=(72+8)/(24) \\ (5x)/(4)=(80)/(24) \\ x=(80\cdot4)/(24\cdot5) \\ x=(320)/(120) \\ x=(8)/(3)\text{ or x }\cong2.667 \end{gathered}

Final answer: So the final answer is x = 8/3 or x = 2.667
