## anonymous one year ago Solve for x: −3|x + 7| = −12 x = 5 over 3, x = −19 over 3 x = −3, x = −11 x = −3, x = 11 No solution

First step is to get the absolutes alone. So divide that -3 over to the other side.

$\left| x \right|=a,x= \pm a$

3. anonymous

$\left| x-a \right|=b,x-a= \pm b$

I keep trying these but I never understand them.

divide by -3 and start with $|x+7|=4$ then solve $x+7=4$ and $x+7=-7$ separately

6. anonymous

both are easy to solve, subtract 7 from both sides

7. anonymous

dang i meant $x+7=4\\ x+7=-4$both are solved by subtracting 7 from both sides

WOW I ACTUALLY GOT IT THANK YOU

Wait I think I got it wrong, I got x = −3, x = 11
