Step-by-step explanation

Since we have the system of equations:

(1) 2x - 4y = 20

(2) x = 4

Plugging in x=4 into (1):

2*4 - 4y = 20

Multiplying numbers:

8 - 4y = 20

Subtracting -8 to both sides:

-4y = 20 -8

Subtracting numbers:

-4y = 12

Dividing both sides by -4:

y = 12 / -4

Simplifying:

y = -3

The solution to the system of equations is (x,y) = (4,-3)
