Answer:
x = 48 and y = 104
Step-by-step explanation:
Given equations are:

From equation 1:

Putting the value of y in equation 2

Now we have to put the value of y in one of the equation to find the value of x
Putting y = 104 in the first equation

Hence,
The solution of the system of equations is x = 48 and y = 104

Answer:
D
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C
Given
5y = -
x - 6 ( multiply through by 4 to clear the fraction )
20y = - x - 24 ( add x to both sides )
x + 20y = - 24 → D
