Solve the equation. |K + 9| = 4
aalyn [17]

Answer:

A) {-13,-5}

Step-by-step explanation:

Given expression:

|K+9|=4

We need to solve for K

Since K+9 lies in the absolute brackets, so we can write the solution as (|x|\ where\ x>0\ and\ x)  :

For K+9>0

K+9=4

For K+9

K+9=-4

Solving for K individually.

Subtracting both sides by 9.

K+9-9=4-9      and K+9-9=-4-9

K=-5              and K=-13

So, the solution can be written as {-13,-5}
