Answer:

f(7) = 68

Step-by-step explanation:

We are trying to find when x = 7, so we should substitute it in the equation.

f(7) = 9(7) + 5

f(7) = 63 + 5

f(7) = 68

What is 8n-(2n-3)=12 ?
bixtya [17]
Okay luv so let's solve this equation together:
8n-(2n-3)=12
simplify
8n+-1(2n-3)=12
8n+-1(2n)+(-1)(-3)=12
8n+-2n+3=12
(8n+-2n)+(3)=12 Combine like terms
6n+3=12
Then subtract from both sides
6n+3-3=12-3
6n=9
Then divide both sides by 6
6n/6=9/6
so...n=3/2
