What is the first step to solving the equation |2x + 1| - 5 = 7? Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. The absolute value of a number can be thought of as the distance of that number from 0 on a number line. Active 8 years, 2 months ago. In the equation y = 3|x-4| + 7, what are the coordinates of the vertex? In mathematics, the absolute value or modulus of a real number x, denoted | x |, is the non-negative value of x without regard to its sign.Namely, | x | = x if x is positive, and | x | = −x if x is negative (in which case −x is positive), and | 0 | = 0.For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3.
