Solution
Explanation:
The initial statement is
[tex]\begin{gathered} y\infty x \\ y=kx \end{gathered}[/tex]when x = 2, y = 14
[tex]\begin{gathered} y=kx \\ 14=k(2) \\ k=\frac{14}{2} \\ k=7 \end{gathered}[/tex]the law connecting y and x
[tex]y=7x[/tex][tex]\begin{gathered} y=7x \\ \text{when x= 22} \\ y=7(22) \\ y=154 \end{gathered}[/tex]Hence the value of the unknown x = 154
