Solve |3x + 9| + 6 = 6
A) x = 3
B) No solutions
C) x = –3
D) x = 3 or x = –3

D

Step-by-step explanation:

3x+9+6=6

step 1 combine like terms

9+6=15

now we have

3x+15=6

step 2 subtract each side by 15

15-15 cancels out

6-15=-9

now we have

3x=-9

step 3 divide each side by 3

3/3 cancels out

-9/3=-3

x=-3

The reason it can also be -3 is because I I means absolute value and the absolute value of negative 3 is positive 3

Have a great day :D
