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

optimism
Explanation:
optimism is not one of the Big five
Applying the definition, it is found that at 
, the value of the function is 9.
The definition of the piece-wise function is:
At x = 3, it enters the second definition, thus:
Thus, the value of the function is 9.
