Question

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

Answer 1

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

Answer 2

\[\left| x \right|=a,x= \pm a\]

Answer 3

\[\left| x-a \right|=b,x-a= \pm b\]

Answer 4

I keep trying these but I never understand them.

Answer 5

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

Answer 6

both are easy to solve, subtract 7 from both sides

Answer 7

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

Answer 8

WOW I ACTUALLY GOT IT THANK YOU

Answer 9

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