What is strategy for finding value of following equation 142divided by n = 28R2?

\frac {142}{n} = 28R2

The "28R2" confuses me. Is that supposed to be 28^2 or 28R^2 or something else?
As written, you have two unknowns, R and n. You can only solve for one of them.
\frac {142}{28R2}= n

\frac{142}{n} = 28R^2
Don't quite understand, since you have two variables, you cannot find the value of n directly. You have to have the value of R. However, making n the subject of formula, we have;
\frac{n}{142} = \frac{1}{28R^2}
\frac{n}{142}\times 142= \frac{1}{28R^2} \times 142
n= \frac{142}{28R^2}
