Solve each system of equations.
2x- 4y = 20
x=4

(x,y)=(4,-3)

Step-by-step explanation:

2x- 4y = 20

x=4

Substitute the value of x

2*4-4y=20

Solve equation

y=-3

A possible solution is

(x,y)=(4,-3)

Check the solution

2*4-4*(-3)=20

4=4

Simplify

20=20

4=4

The ordered pair is the solution

i think asking google will you get the answer to that question
