How many solutions does the equation have?

Question

|q| + 2 = 2
no solution
one solution
two solutions

Answer 1

The equation given is |q| + 2 = 2. To solve for q, we can subtract 2 from both sides of the equation:

|q| = 2 - 2
|q| = 0

The absolute value of any number is always non-negative. Therefore, the only possible solution for q in this case is q = 0.

So, the equation has one solution: q = 0.
