![f(x) = \frac{2}{x} \\\\g(x) = \frac{2}{x}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B2%7D%7Bx%7D%20%5C%5C%5C%5Cg%28x%29%20%3D%20%5Cfrac%7B2%7D%7Bx%7D)
(fog)(x)= ![\frac{2}{\frac{2}{x}} = \frac{2x}{2} = x](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B%5Cfrac%7B2%7D%7Bx%7D%7D%20%3D%20%5Cfrac%7B2x%7D%7B2%7D%20%3D%20x)
Answer:
n+3 = 15 ; n = 12
3n -6 = 12; n=6
Step-by-step explanation:
more than means it comes after
a number
n
3 more than
n+3
is 15
n+3 = 15
Subtract 3 from each side
n+3-3 = 15-3
n = 12
Subtract from comes after
three times a number
3n
six subtracted from
3n -6
is 12 means equal to
3n -6 = 12
To solve add 6 to each side
3n -6+6 =12+6
3n = 18
Divide by 3
3n/3 =18/3
n =6
