Solve for x: |x − 2| + 10 = 12

 x = 0 and x = 4


 x = −4 and x = 0
 x = −20 and x = 4
 No solution

first you can add -10 on both sides so you gonna have :
l x - 2 l = 12 - 10 ⇒ l x - 2 l = 2 now because of the absolute value you should say :
1) x - 2 = 2 ⇒ x = 2 + 2 ⇒ x = 4

2) x- 2 = -2 ⇒ x = -2 +2 ⇒ x = 0
so the answer is first one :)))
i hope this is helpful
have a nice day

Let's solve this equation step-by-step!
is the question you've asked us today:
|x − 2| + 10 = 12

Add -10 to both sides:
|x−2|+10+−10=12+10

Solve Absolute Value:
|x−2|=2

✯We know either:
x−2=2 or x−2=2

(Possibility 1) x−2=2

(Add 2 to both sides) x−2+2=2+2

x=4

(Possibility 2) x−2=−2

(Add 2 to both sides) x−2+2=−2+2

x=0

✯So since we have gotten x=4 and x=0 you answer shall be:

B. x=4 and x=0

✯I hope this helps!
