Multiply first equation by 8, 
24x + 40y = 352
Multiply second equation by 3, 
24x - 21y = -75

Now, subtract second from 1st, 
61y = 427
y = 427/61
y = 7

Substitute it in very first equation, 
3x + 5(7) = 44
3x = 44 - 35
x = 9 / 3
x =3

In short, Your Answer would be Option D) (3, 7)

Hope this helps!

(note that 0.45 is 450g in Kg, When adding things such as weight or length you want to make sure that they are all in the same unit)

Step-by-step explanation:

Given the functions as:

f(x)=2x+210
