Answer:x1=-15;x2=7
Step-by-step explanation:
|x+4|+10=21
|x+4|=21-10
|x+4|=11
x+4=11
x+4=-11
x=7
x+4=11
x=7
×=-15
The equation has 2 solutions
x1=-15 x2=7
Answer: x = 7, x = -15
Step-by-step explanation:
This is an absolute value equation, so it has to be simplified first
|x+4|+10=21
|x+4|=11
Then you set it equal to the two values it can be, getting rid of the absolute value sign.
x+4=11
x+4=-11
x = 7
x = -15
Voila!
