Answer:
1.) 0
2.) b = -0.8333333333
3.) -x-22
Step-by-step explanation:
Pull out like factors : -3x - 2 = -1 • (3x + 2)
(-5 • (3x + 2) - (x - 3)) - (-16x - 7) = 0
Pull out: -16x-7
After pulling out, we are left with: (-16x-7) • ( 1 +( (-1) ))
Pull out like factors: -16x - 7 = -1 • (16x + 7)
0 = 0

Simplifying
2(a + -3) + 4b + -2(a + -1b + -3) + 5 = 0
Reorder the terms:
2(-3 + a) + 4b + -2(a + -1b + -3) + 5 = 0
(-3 * 2 + a * 2) + 4b + -2(a + -1b + -3) + 5 = 0
(-6 + 2a) + 4b + -2(a + -1b + -3) + 5 = 0
Reorder the terms:
-6 + 2a + 4b + -2(-3 + a + -1b) + 5 = 0
-6 + 2a + 4b + (-3 * -2 + a * -2 + -1b * -2) + 5 = 0
-6 + 2a + 4b + (6 + -2a + 2b) + 5 = 0
Reorder the terms:
-6 + 6 + 5 + 2a + -2a + 4b + 2b = 0
Combine like terms: -6 + 6 = 0
0 + 5 + 2a + -2a + 4b + 2b = 0
5 + 2a + -2a + 4b + 2b = 0
Combine like terms: 2a + -2a = 0
5 + 0 + 4b + 2b = 0
5 + 4b + 2b = 0
Combine like terms: 4b + 2b = 6b
5 + 6b = 0
Solving
5 + 6b = 0
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '-5' to each side of the equation.
5 + -5 + 6b = 0 + -5
Combine like terms: 5 + -5 = 0
0 + 6b = 0 + -5
6b = 0 + -5
Combine like terms: 0 + -5 = -5
6b = -5
Divide each side by '6'.
b = -0.8333333333
Simplifying
b = -0.8333333333
_______________________________________
|x - 2| - 4*|-6|
=|x - 2| - 4* 6
=|x - 2| - 24
x-2>=0 then x>= 2 and = x-2-24 = x-26
x-2<0 then x<2 and = 2-x-24 =-x-22
so
, If x>=2 then the expression will equal x-26
&
If x<2 then the expression will equal -x-22
