Question

|x+12|=3 хелппппппппп​

Answer 1

$|x + 12| = 3 \\ x + 12 = + - 3 \\ x1 = - 9 \\ x2 = - 15$

Answer 2

Looks like you've got an absolute value equation on your hands! To solve it, you can split it into two cases:

1. $x + 12 = 3$
2. $x + 12 = -3$

For the first case, subtract 12 from both sides to find the value of $x$. And for the second case, do the same but remember to flip the sign. What do you get?
