Answer:
3
Step-by-step explanation:
Write down the expression exactly as it is given.
[tex] \dfrac{3y - 9}{x} = [/tex]
Now write the expression again, but replace x with 3, and replace y with 6.
[tex] = \dfrac{3 \times 6 - 9}{3} [/tex]
Now simplify the numerator using the correct order of operations.
[tex] = \dfrac{18 - 9}{3} [/tex]
[tex] = \dfrac{9}{3} [/tex]
Now divide 9 by 3.
[tex] = 3 [/tex]
