Step-by-step explanation:

1. X=12

X= -12

2. X=5

X= -5

3. 2|x|=24

= 2|X|/2 = 24/2

=. |X|=12

= X=12

=X= -12

4.|5x+4|+12=4

= |5x+4| -12=4

= |5x+4| =4

=|5x-4|=4

=|5x|=4

= 5x/5 =4/5

X=4/5 or 0.8

X= -4/5 or -0.8

5. |2x|=8

2x/2 =8/2

X=4

X= -4

6. 4|2x-5| -2=10

= 4|2x-5| +2=10+2

= 4|2x-5|/4 =12/4

= |2x-5|=3

=|2x+5|=3

|2x|=3

2x/2 =3/2

X=3/2 or 1.5 or x= -3/2 or -1.5

7. |2x-5|=9 there are 2 solutions so:

first:

= 2x - 5=9

2x + 5 =9+5

2x/2= 14 /2

X=7

=2x-5=-9

2x + 5= -9+5

=2x= -4
