What is Linear Equation?
A linear equation is one where x appears only to the first power, so the graph is a straight line and there is at most one answer. Solving is two moves: take b to the other side, then divide by a.
How it works
The tool isolates x by subtracting b from both sides and dividing by a, printing each step. When a is zero the equation stops being about x at all — it is either true for every number or for none — and the tool says which rather than dividing by zero.
