<h3>
Answer: B) no solutions</h3>
===========================================================
Explanation:
Let's isolate the variable y in the first equation
-2x - y = 1
-2x = 1 + y
1+y = -2x
y = -2x-1
Then we'll plug this into the second equation
-4x - 2y = -1
-4x - 2(-2x-1) = -1
-4x + 4x + 2 = -1
0x + 2 = -1
0 + 2 = -1
2 = -1
We run into a contradiction. No matter what x value we pick, the last equation will never be true. This leads to a domino effect to cause the first set of original equations to never be true when considered as a system.
Therefore, this system is inconsistent. There are no solutions. These two lines graph out parallel lines that never intersect.

Answer:
There are total 96 shirts out of which 72 are black and 12 are white and 12 are red.
Step-by-step explanation:
Let the total number of shirts be x.
Then 3/4= 0.75 shirts are black
50% or 50/100 =0.5 of 1/4 ( 1-3/4) remaining are white
and 12 are red
x= 0.75x+0.125x+12
x= 0.875x+ 12
x-0.875x= 12
0.125x= 12
x= 12/0.125
x= 96
There are total 96 shirts out of which 3/4 are black
96*0.75= 72 are black and
96*0.25= 24 are left behind out of which 50% are white.
12 are white and 12 are red.
