Solution

Step-by-step explanation:

The initial statement is


\begin{gathered} y\infty x \\ y=kx \end{gathered}

when x = 2, y = 14


\begin{gathered} y=kx \\ 14=k(2) \\ k=(14)/(2) \\ k=7 \end{gathered}

the law connecting y and x


y=7x
\begin{gathered} y=7x \\ \text{when x= 22} \\ y=7(22) \\ y=154 \end{gathered}

Hence the value of the unknown x = 154
