Answer:

a can be any real number less than equal to -5

Step-by-step explanation:

When a+5 is negative,

a + 5 = -(-5 - a)

a + 5 = a + 5

All values satisfy the equation

So a < -5

When a + 5 is greater than/equal to 0,

a + 5 = -a - 5

2a = -10

a = -5

a can be any real number less than equal to -5
