Answer:
GCF = 20
Step-by-step explanation:
he answer would be 20 so then you would get (3-2y) as a final answer
here you go,
8
B
(5,4)
-x+2y=3
3x-2y=7
Add the like terms( 2y and -2y)(-x and 3x)(3 and 7) together. Do this vertically. 2y and -2y cancel eachother out.
Divide both sides by 2
To find y, substitute x in for y in one of the equations
add 5 to both sides
