The answer is 42
Step-by-step explanation:
GIVEN:
G(x) = {x-3}
G(x) = 39
To find:
The value of x
SOLUTION:
Let G(x) = {x-3} be the first equation and
G(x) = 39 be the second equation.
Substitute second equation in the first equation,
39 = {x-3}
39 + 3 = x
42 = x
The value of x = 42. Therefore x = 42.
