Do i put on in numbers to figure out answer?

Question

g(x)=17, x=?

the info given is g(x)=7/2x+10

do I put 

g(7/2x+10)=17

do I figure like this?

Answer 1

You are given the equation:

 

g(x) = (7/2)x + 10

 

You are also given a specific value for g(x):  g(x) = 17

 

Substitute 17 for g(x) in the given equation and solve for x:

 

17 = (7/2)x + 10

 

Solve for x and get

 

x = (2/7)(17 - 10) = 2
