Question

Which pair of equations could not be used to solve the following equations for x and y?
4 + 2 = 22
−2 + 2 = −8

A.4 + 2 = 22 B. 12 + 6 = 66 C. 4 + 2 = 22 D. 8 + 4 = 44
2 − 2 = 8 6 − 6 = 24 -4x + 4y =-16 -8x + 8y = -8

Answer 1

Answer: 4

Step-by-step explanation:

I was looking for the answer for this question for my own homework, and the answer is four on mine, however this post wasn't clearly formatted so I can't tell the difference between answers...

For those of you who are here from a g00gle search:

THE ANSWER IS:

8x + 4y = 44

-8x + 8y = -8

BECAUSE ONLY ONE SIDE OF THE SECOND EQUATION WAS MULTIPLIED BY FOUR
