Hey there Smarty!
[tex]\boxed{\boxed{Rearrange \ the \ equation \ by \ subtracting}}[/tex]
[tex] \left[\begin{array}{ccc}\boxed{\boxed{ 7*x/15-1-(22)=0 }}\end{array}\right] [/tex]
[tex]\boxed{((7* \frac{x}{15)}-1)-22=0}} [/tex]
[tex] \left[\begin{array}{ccc} \frac{(7x - 15) }{15} -22=0\end{array}\right] [/tex]
[tex]Add \ 345 \ to \ both \ sides \ of \ the \ equation : \\ \\
7x = 345 \\ \\ Divide \ both \ sides \ of \ the \ equation \ by \ 7:
x = 345/7 = \boxed{\boxed{49.28}}
[/tex]
Hope this helps you!
