First, you need to substitute y for 2/3:
2/3 • 6
Next, change 6 into a fraction and multiply straight across:
2/3 • 6/1
12/3
Finally, simplify it to its simplest form:
4
Your answer should be 4.
Hopefully that helped!
Answer:
12a^2 - 9a + 5
Step-by-step explanation:
(5a^2 - 6a - 4) - (-7a^2 + 3a - 9)
5a^2 + 7a^2 = 12a^2
-6a - 3a = -9a
-4 + 9 = 5
12a^2 - 9a + 5
