Answer:
A two-step equation is something like:
A*X + B = C
In this case, like in a linear equation, we have only one solution that can be found as:
A*X = C - B
X = (C - B)/A
In the case of a two-step inequality, we have something like:
A*X + B > C
Solving this we get;
A*X > C - B
X > (C - B)/A
In this case, any value of X that is larger than (C - B)/A is a solution, so in this case, we have infinite solutions.
That is the difference between the number of solutions for each case, in a two-step equation we have only one, while in the case of the inequality we have infinite.
Answer:
I am pretty sure it is most likely answer D.

Hope this helps! Have a great day and good luck!
Yes, it is helpful to show the equivalent decimal
A = A
B = 3A + 18
C = A + 42
The sum of the angles of a triangle equals 180°
A + B + C = 180
(A) + (3A + 18) + (A + 42) = 180
5A + 60 = 180
5A = 120
A = 24
B = 3A + 18 = 3(24) + 18 = 72 + 18 = 90
C = A + 42 = C = 24 + 42 = 66
Answer: A=24, B=90, C=66
