Answer 3

8=|6+2n|-4

8+4=|6+2n|-4+4 ... add 4 to both sides

12 = |6+2n|

|6+2n| = 12


making sense so far?

Answer 4

Let's solve your equation step-by-step.
8=|6+2n|−4
8=|2n+6|−4
Step 1: Flip the equation.
|2n+6|−4=8
Step 2: Add 4 to both sides.
|2n+6|−4+4=8+4
|2n+6|=12
Step 3: Solve Absolute Value.
|2n+6|=12
We know either 2n+6=12 or 2n+6=−12
2n+6=12(Possibility 1)
2n+6−6=12−6(Subtract 6 from both sides)
2n=6
2n
2
=
6
2
(Divide both sides by 2)
n=3
2n+6=−12(Possibility 2)
2n+6−6=−12−6(Subtract 6 from both sides)
2n=−18
2n
2
=
−18
2
(Divide both sides by 2)
n=−9
Answer:
n=3 or n=−9

Answer 5

i just dont get this part =
−18
2
(Divide both sides by 2)
n=−9
Answer:
n=3 or n=−9
