The root of the equation ax + b = 0 is x = ?

Explanation:
When solving a linear equation in x, you want to isolate x. Move b to the other side to get ax = -b, then divide by the coefficient a (assuming a ≠ 0). This yields x = -b / a, which is the value that makes ax + b equal to zero. If a = 0, the equation becomes b = 0: no solution when b ≠ 0, and every x satisfies the equation when b = 0. In the usual case with a ≠ 0, the root is -b divided by a.
