two solutions

1 answer

The equation 14 = |d| + 5 can be written as |d| = 9. This means that the absolute value of d is equal to 9.

The absolute value of a number can never be negative, so the only possible values for d are 9 or -9. Therefore, there are two solutions for the equation: d = 9 and d = -9.
