28 - 2.2x = 11.6x - 54.8
28 + 54.8 = 11.6x + 2.2x
82.8 = 13.8x
82.8 / 13.8 = x
6 = x
or x = 6
If you apply the linear combination method to the system like:
<span>4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
Then you can be sure that the solution of all this system is: (9,3). Hope this si what you were looking for</span>
Answer:

Step-by-step explanation:
We see that the two terms share an x, so we can pull that out:

Now notice that we have a difference of squares (
). Given a difference of squares,
, this can always be factored into
. We can use this in this case:
.
So, our final factorized form is:
.
Hope this helps!
