Question

Which ordered pair makes both of these equations true?

Answer 1

D is the answer im sure

Answer 2

Answer:

D. (3, -1)

Step-by-step explanation:

y = 2x - 7 and 4x + y = 11 are two given equation

Now, Name the equation

y = 2x - 7 ...(1)

4x + y = 11 ...(2)

Then, Put the value of y in equation (2)

4x + y = 11

4x + (2x - 7) = 11

4x + 2x - 7 = 11

6x - 7 = 11

6x = 11 + 7

6x = 18

x = 18/6

x = 3

Here, put the value of x in equation (1)

y = 2x - 7

y = 2(3) - 7

y = 6 - 7

y = - 1

Thus, (3, - 1) pair makes both of these equations true
