Answer:

No solution

Explanation:Given the system of eqations:


\begin{gathered} y+(1)/(2)x=3 \\ 4y+2x=6 \end{gathered}

From the second equation, find x.


\begin{gathered} 2x=6-4y \\ x=(6-4y)/(2) \\ =3-2y \end{gathered}

Substitute the obtained value of x into the first equation.


\begin{gathered} y+(1)/(2)(3-2y)=3 \\ y+(3)/(2)-y=3 \\ (3)/(2)=3 \end{gathered}

which isnotpossible. So, no solution exists.
