Solve the system using elimination.
4x + 7y = 39
6x - 7y = - 29
The solution is

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

( 4x + 7y = 39 )

x = −7 / 4y + 39 / 4

y = −4 / 7x + 39 /7

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

( 6x - 7y = - 29 )

x = 7 / 6y + −29 / 6

y = 6 / 7x + 29 / 7

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

step-by-step explanation:

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
