The solutions for this absolute value problem are:

A.) x = 3 & x = -3
B.) x = 11 & x = -3
C.) x = -11 & x = 3
D.)x = -11 & x = 11

13.) |2x + 4| = 2
A.)x = -2 & x = -6
B.) x = 2 & x = 6
C.) x = -1 & x = 3
D.) x = 1 & x = -3
E.) x = -1 & x = -3

14.) 2x - 17 = 4(x - 3) + 1
x = ?

15.) -6y - 6 = 30
y = ?

16.) -2(x - 5)
A.)-2x - 5
B.) -2x - 10
C.) -2x + 10
D.)-2x + 5

Answer 1

You really need to make the attempt first. Once I can see that you have tried, I'll help you out.

Answer 2

12) subract 6
divide by 2
x=7 or -7, so first subract 4 from 7, and then from -7.
answer: x=3 or -11
if there was a less than or greater than sign instead of the = sign, you would have reversed it
do 13, 14 yourself the same way
15) add 6 to both sides
divide both sides by -6

Answer 3

12 is A.
14 is x = -5.
15 is y = -6.
16 is A.
13 however, I do not know.
=/

Answer 4

12. c
13. d
14. x= -3
15. y= -6
16. c
