(3 * n) +4 = 16
(3 * n) = 12
n = 4
(2n - 9) - 5(-2.4n + 4) =
The first set of parentheses is unnecessary, so we just drop them.
= 2n - 9 - 5(-2.4n + 4)
Now we distribute -5 by the second set of parentheses. Each term in the parentehses is multiplied by -5.
= 2n - 9 + 12n - 20
Now we combine like terms.
= 2n + 12n - 9 - 20
= 14n - 29
Answer:
Subtract 24 from both sides
Now, subtract 6x from both sides
Multiply both sides by -1
Divide 18 from both sides
