@hallway look at your original post
okay I figured it out!! Thank you
it was choice B
x=18, x=-6 is what it should be
Solve for x: −3|x + 7| = −12 so for this problem, I start by adding -12 to both sides?
no you don't need to do that now, just divide -3 to both sides
okay thank you! How do you know when to divide and when to subtract/add?
because there is a negative next to the three
-3 is a number so we treat the equation by saying divide both sides by -3 so we can get rid of the number on the left side
I got -1 | x + 7 | = -4 Okay that makes sense, thanks
|x+7|=4 x=+4-7 and x=-4-7 therefore x=-3 and x=-11
yep good job
Solve for x: |x − 2| + 10 = 12
x = 0 and x = 4 x = −4 and x = 0 x = −20 and x = 4 No solution these are the options, and I got | 0 - 2 | =2
replace 0 with the x, it didn't disappear
okay and then for this equation, |x| - 8 = - 5 I got x=3
I added 8 to both sides
x = −13 and x = −3 x = 3 and x = −3 x = 3 and x = 13 No solution those are the options and I chose B, correct?
x = 3 and x = −3
okay thank you so so so so so much!!
This is the first website that has actually helped me! I am doing an online math class and it can be really difficult not having a teacher around to answer my questions, you helped a ton thankless
