Final answer:
The value of y, when x is -7, is 10.
Step-by-step explanation:
The absolute value of a number is its distance from zero on a number line. When given a value for x, to find the value of |x| we simply take the positive version of that value. So if x = -7, then |x| = 7.
Next, we add 3 to the absolute value of x. In this case, y = |x| + 3 = 7 + 3 = 10.
Therefore, if x is -7, then y is 10.
