X-4y=16 and 5x-5y=45 solve for x

i got 86 for this

hope this !

if you need an explanation just ask

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
