Answer:

(5/2 , 1)

Step-by-step explanation:

4X – 3y = 7

4x + y = 11

———————

Multiply a -1 to the bottom equation to get the 4x as a negative so it cancels out.

4x - 3y = 7

-4x - y = -11

——————

-4y = -4

Divide by -4

y = 1

Substitute the value of y into one of the equations and solve

4x - 3(1) = 7

4x -3 = 7

4x = 10

Divide by 4

X = 10/4

Simplify by dividing by 2

x = 5/2

Therefore the answer is (5/2, 1 )

Katena32 [7]
I think the appropriate response is Independent Verification. It is voting machines that create no less than two free auditable records of votes where the second record is utilized to check the first. To be viewed as "free" no less than one of the records must not be editable by the voting machine and be straightforwardly irrefutable by the voter. These frameworks must take into consideration the numerous records to have the capacity to be cross-checked.
