8x - 9y = 11 (subtract 8x from each side)
- 9y = -8x + 11 (divide -9 from each side)

y =
D.
You have to use distributive property. Multiply the numbers outside of the parenthesis by the numbers inside. For example, you would multiply 0.4 by 2x first, then multiply it by 1/2. You should get two answers. Write them down in this form: first answer + second answer. Then do the same for the other side of the equal sign, but leave the - 4 alone.

Answer:
n=5/4 or n=-1/4
Step-by-step explanation:
16n^2 - 10n-5=6n
16n^2-16n-5=0
(4n)^2-2.4n.2+2^2 = 2^2 + 5
(4n- 2)^2=9
4n-2 = 3 or 4n-2=-3
4n=5 or 4n=-1
n=5/4 or n = - 1/4
Answer:
the answer would be 2 and 1/2
