Answer:


x=-8(1)/(3)

Step-by-step explanation:

Given the equation


(1)/(5)x+(1)/(2)=3+(1)/(2)x

We begin by collecting like terms as follows:


(1)/(5)x-(1)/(2)x=3-(1)/(2)

Next, we take the lowest common multiples of the denominator on each side.


\begin{gathered} (2x-5x)/(10)=(6-1)/(2) \\ -(3x)/(10)=(5)/(2) \end{gathered}

We cross-multiply


\begin{gathered} -3x*2=10*5 \\ -6x=50 \end{gathered}

Finally, apply the division rule of equality.


\begin{gathered} -(6x)/(-6)=(50)/(-6) \\ x=-8(2)/(6) \\ x=-8(1)/(3) \end{gathered}
