Answer:
-5/7
Step-by-step explanation:
We need to find g(7) first
All we have to is plug 7 in the place of x
g(7) = 1/7
Now we have f(1/7) = 2x - 1
f(1/7) = 2(1/7) - 1
f(1/7) = 2/7 - 1
Don't forget about common denominators
2/7 - 7/7 = -5/7
The solution is x= 3 and y = 1
Step-by-step explanation:
Given equations are:

From equation 1:

Putting in equation 2:

Dividing both sides by -9

Putting y = 1 in equation 1:

Hence,
The solution is x= 3 and y = 1
