Question

|3t+6| =9

A. n= -5
B. n= 1
C. n= -1 or 1
D. n= -5 or 1

Answer 1

C, n= -1 or 1.

Step-by-step explanation: The bars around 3x+6 are absolute value bars (| |), meaning that whatever lies inside of them will turn positive. An example: |-9| ➡️ 9. So, since we do have the absolute value bars, multiplying 3 by -1 would not effect the equation. So therefor we could use a regular 1 or a negative one to make the equation equal to 9.
