<span>We want to show that f(g(x)) = x and g(f(x)) = x. So to do that, we need to calculate f(g(x)) and g(f(x)) explicitly. Let's begin with f(g(x)) Now, f(g(x)) = f(4/x), by definition of g, as g(x) = 4/x What then is f(4/x) equal to? Use the definition of f.</span>

9x-7=-7 what does x equal

horsena [70]

Answer:

x = 0

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.

First, add 7 to both sides:

9x - 7 (+7) = - 7 (+7)

9x = -7 + 7

9x = 0

Next, divide 9 from both sides:

(9x)/9 = (0)/9

x = 0/9 = 0

x = 0 is your answer.
