If G(x) = 39, then

5/2x - 7/2 = 39

Multiplying both sides by 2, we get

5x - 7 = 78

5x = 78 + 7

5x = 85

x = 17

I hope this answer helps!

Answer:

x=17

Step-by-step explanation:

Given that G(x)=5/2x-7/2

Given that G(x)=39

Which is 39=5/2x-7/2

Multiply through by 2

39×2=(5/2x)2 - (7/2)2

78=5x -7

5x=78+7=85.

x=85/5

x=17.
