How do I answer
|V|+15=24

v = ± 9

Step-by-step explanation:

The absolute value function always gives a positive result, however, the expression inside can be positive or negative, that is

| - a | = | a | = a

Given

| v | + 15 = 24 ( subtract 15 from both sides )

| v | = 9 , thus

v = ± 9

v = +/- 9

Step-by-step explanation:

|v| + 15 = 24

we draw two equation:

v + 15 = 24 -v + 15 = 24

v = 24 - 15 15 - 24 = v

v = 9 -9 = v

hence v = +/- 9

note: |-v| = |v| = v.
