Answer:

x=2; y=-1

Step-by-step explanation:

Hello,

(1) 6x+7y=5

(2) 2x-3y=7

We multiply equation (2) by 3, it gives

6x-9y=21 and we subtract from (1)

6x-9y-6x-7y=-16y=21-5=16

So y = -1

we replace in (1) 6x-7=5 <=> 6x=7+5=12 <=> x =12/6=2

thanks

Black_prince [1.1K]

Answer: 1/x + 7

Step-by-step explanation: you plug the function g(x) into the function f(x) .. substitue g(x) for the x in f(x)

G(x) = 1/x , so you plug that in the x of f(x) and get 1/x + 7
