Use the elimination method to solve the system of equations. Choose the correct ordered pair.
7x+4y= 39
2x + 4y = 14
A. (3,2)
B. (5,1)
C. (5,4)
D. (3,4)

The answer is B.

Step-by-step explanation:

When Elimination method is applied, you have to eliminate one of the variables from both equations. Firstly, both equations contain 4y so you can subtract it :

Next, you have to substitute x = 5 to any equations. I will choose to put in (2) :

Therefore, put your answer in coordinate form :

a - base

b - exponent

so,

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
