Solve:
1/(c−3) − 1/c = 3/[c(c−3)].

Combine the left side over common denominator c(c−3):
[ c − (c−3) ] / [c(c−3)] = [3]/[c(c−3)].

So the equality is an identity for all c for which the expression is defined. The expression is undefined at c = 0 and c = 3 (division by zero), so the solution is all real numbers except c = 0 and c = 3.
