Answer:

Yes, both equations will always work, but yes, at times it is more logical to use one over the other. for instance:

x-4y=6

x+4y=12

we see here that elimination would best fit:

x+x+4y-4y=6+12

or:

x=2y-3

7x+3y-81=23

substitute (2y-3) for x.

Also, once you have a single placeholder, put it ito quadratic form (ax^2+bx+c=0)

and use the quadratic formula:

x=(-b±sqrt(b^2-4ac))/2a

I think there is only one 4

as following 4,8,12,20

4+8=12

8+12=20

20+12=32

20+32=52

52+32=84

84+52=136

136+84=220

136+220=356

so 4,8,12,20,32,52,84,136,220,356
