Question

$$1 \frac { 1 } { 2 } + 2 \frac { 2 } { 7 } = 3 \frac { 1 } { 2 } + ?$$

Answer

l=(J+85)/(112*So*e*v)

Solution


Regroup terms.
\[112Soelv+227=312+J\]
Subtract \(227\) from both sides.
\[112Soelv=312+J-227\]
Simplify  \(312+J-227\)  to  \(J+85\).
\[112Soelv=J+85\]
Divide both sides by \(112\).
\[Soelv=\frac{J+85}{112}\]
Divide both sides by \(So\).
\[elv=\frac{\frac{J+85}{112}}{So}\]
Simplify  \(\frac{\frac{J+85}{112}}{So}\)  to  \(\frac{J+85}{112So}\).
\[elv=\frac{J+85}{112So}\]
Divide both sides by \(e\).
\[lv=\frac{\frac{J+85}{112So}}{e}\]
Simplify  \(\frac{\frac{J+85}{112So}}{e}\)  to  \(\frac{J+85}{112Soe}\).
\[lv=\frac{J+85}{112Soe}\]
Divide both sides by \(v\).
\[l=\frac{\frac{J+85}{112Soe}}{v}\]
Simplify  \(\frac{\frac{J+85}{112Soe}}{v}\)  to  \(\frac{J+85}{112Soev}\).
\[l=\frac{J+85}{112Soev}\]
