The equation "ax + b = c" is a linear equation in one variable, where a, b, and c are constants, and x is the variable we want to solve for. The term a represents the coefficient of x, which indicates how much x is multiplied by, while b is a constant added to the product. The goal is to find the value of x that makes the equation true. To solve for x, you can rearrange the equation by isolating x on one side. First, subtract b from both sides to get "ax = c - b." Then, divide both sides by a to find x = (c - b)/a. This process allows you to determine the value of x that satisfies the equation.
