The solution to the system of equations is x = 30 and y = -36.
The two equations are known as simultaneous equations. The elimination method would be used to determine to find the solutions.
−3x−9y=18 equation 1
4x+3y=12 equation 2
In order to determine the value of x, take the following steps;
Multiply equation 2 by 3
12x + 9y = 36 equation 2
Add equation 1 and equation 2
x = 30
Substitute for x in equation 2
4(30) + 3y = 12
120 + 3y = 12
120 - 12 = -3y
108 = -3y
y = 108 / -3 = -36

The type of mood that the above setting from Jekyll and Hyde creates is a creepy one. This is evident from the use of words like "sinister block", "gable on the street", and "showed no window", all of which foreshadow an eerie presence to the reader.
A setting might be a true time and place, or it can be a fictional universe and an unknown time. Along with the physical surroundings that provide a backdrop for the action, the setting also refers to the climatic conditions, the weather, and the social and cultural context. An account's exposition reveals the setting.
