2.5*7 = 17.5. If it's easier for you, multiply 2.5 by 5 then add 2.5*2.
I would use subsitution
y=x-7
sub x-7 for every x
5x+2(x-7)=14
5x+2x-14=14
add 14 to both sides
7x=28
divide both sides by 7
x=4
sub
y=x-7
y=4-7
y=-3
x=4
y=-3
(4,-3)

I don't know if i'm right for sure but I really hope this helps you! :)
Answer:
Option D) 
is correct
Therefore 
Step-by-step explanation:
Given polynomial is 
To factorise the given polynomial by taking out the common terms of the given polynomial :
( here 2y is GCF common term so taking outside the terms of the polynomial )
( now taking (-) outside )
Therefore
Option D) is correct
