    ? A linear equation in one variable
    A linear equation in one variable is an equation that can be written in the form:
    ax + b = 0
    where a and b are constants

    The following is an example of a linear equation in one variable:
    7x - 1 = 6

    Solution of a linear equation in one variable is a value, such that, when you replace the variable with it, it makes the equation true (the left side comes out equal to the right side).

    Example: Solve x - 10 = -1 for x.

    x - 10 ...
