Answer:
x=1
You solve for x by cross multyplying
Answer:
, 
Step-by-step explanation:
<h3>
I will use the elimination method.</h3>
We want to make the X's the same:


Because the signs of the X's are the same we subtract the 2 equations to make:
(I put the second one on top of the 1st)

So:

Substitute y into either equation 1 or 2:
(I chose equation 1)



So:

The multiples of 14 are 1,2,7,14
the multiples of 22 are 1,2,11,22
Therefore 2 is the GCF
25 * 5 + 15 * 3 - 40 * 2 =
125 + 45 - 80 =
170 - 80 =
90
