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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

I keep trying these but I never understand them.

anonymous · Answer

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

anonymous · Answer

both are easy to solve, subtract 7 from both  sides

anonymous · Answer

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

anonymous · Answer

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