Solve for the indicated variable

Question

K=IR/E solve for I.

Answer 1

K=IR/E Need to solve for I, so need to move the R and E variables to the other side.

If multiply both sides by E/R, the right side terms will cancel out, isolating the I term.

Or can do in two steps: Mult both sides by E, then divide both sides by R (or in reverse order).
