So I've been trying for the last hour, to no avail. p = 2+j/J-3 Rearrange the formula so j is the subject.

p = 2+j/J-3 The equation as your wrote it is ambiguous. Please rewrite in a non ambiguous way. eg, do you mean: $\displaystyle p = \frac{2+j}{j-3}$ or $\displaystyle p = \frac{2+j}{j} -3$ or...etc
$\displaystyle p = \frac{2+j}{j-3}$
$\displaystyle p=\frac{2+j}{j-3}$ (multiply by [j-3]) $\displaystyle (j-3)p={2+j}$ expand the brackets on the left, collect terms, and finish. Spoiler: $\displaystyle (j-3)p={2+j}$ $\displaystyle jp-3p={2+j}$ $\displaystyle jp-j -3p=2$ $\displaystyle j(p-1) -3p=2$ $\displaystyle j(p-1) =2+3p$ $\displaystyle j=\frac{2+3p}{(p-1)}$ EDIT: spoiler added
