Question

3 1/8x - 22/5 + 22/5= 7 1/2
3 1/8x= 15/2 + 22/5
25/8x - 25/8= 15/2 + 22/5
25/8x= 3/1 + 11/1
25/8x - 25/8= 14/1- 25/8
x=7/1-25/4
x=18/4
x= 4-1/2

Is this right?

Answer 1

is x in the denom?

Answer 2

Hmm good question @amistre. I took it to be as follows:
\[\Large \begin{array}{l}
{\rm{3 1}}/{\rm{8x }} - {\rm{ 22}}/{\rm{5 }} + {\rm{ 22}}/{\rm{5}} = {\rm{ 7 1}}/{\rm{2}}\\
3\frac{1}{8}x - \frac{{22}}{5} + \frac{{22}}{5} = 7\frac{1}{2}\\
\frac{{25}}{8}x = \frac{{15}}{2}\\
x = \frac{{\frac{{15}}{2}}}{{\frac{{25}}{8}}}\\
x = \frac{{8 \cdot 15}}{{25 \cdot 2}} = \frac{{120}}{{50}} = \frac{{12}}{5}
\end{array}\]

Answer 3

the wolf pops out x=1/36 if under; and x=36 if not

Answer 4

I think the Wolf and I are misunderstanding each other. If (3+(1/8))x then:
