We have that
using a graph tool
<span>I proceed to verify each case to get the answer
</span>see the attached figure
case A)
y> 2x-4 y>=-x y<=3
case B)
y> 2x-4 y>=-x y<3
case C)
y< 2x-4 y>=-x y<=3
the answer is the option A)
y> 2x-4 y>=-x y<=3
115>5.75x+28.75
5.75x+28.75<115
5.75x<115-28.75
5.75x<86.25
x<86.25/5.75
x<15 or (-∞,15)
Answer: x<15 or (-∞,15)
The solution is: x=5, y=2

Hello,
A is True
-x-4=8==>x=-12
or -(-x-4)=8==>x=4
B is false
|0.5x-42.1| is always >0
but -20.6/3.4<0 ==> no solution
C: ? not a equation
D is false |2x-10|=-20has no solution
E: ? not an equation
I don't know what you expected!
2(x - 4) - 6(2x - 3) = 0
Distribute the 2 and the 6 using the distributive property, which is: a(b+c) = ab + ac
2x - 8 - 12x + 18 = 0
Simplify
-10x + 10 = 0
Add 10 on both sides
-10x = -10
Divide -10 on both sides
-10x/-10 = -10/-10
x = 1
Your final answer is d. x = 1.
