-6n - 14 = 18 + 10n
-6n - 10n = 18 + 14 (Move all the similar parts to one side, taking note of sign functions)
-16n = 32 (simplify)
n = 32/-16 (divide)
n = -2
----
2/3a + 9 = 1/3a + 18
2/3a - 1/3a = 18 - 9 (move over like signs, etc...)
1/3a = 9 (divide)
27a = 1 (cross multiply)
a = 1/27 (divide)

-6n - 14 = 18 +10n
-6n -14 +6n = 18 + 10n + 6n (collect all variables on one side)
-14= 18+16n
-14 - 18= 18+ 16n - 18 (isolate the letter)
-32= 16n
-32/16= 16n/16 (get rid of the number next to the letter)
-2=n
2/3a+9= 1/3a+18
2/3a+9- 1/3a= 1/3a+18- 1/3a (collect all variables on one side)
1/3a+9= 18
1/3a+9-9= 18-9 (get the a by itself)
1/3a= 9
3X 1/3a =9 X 3 (Get a by itself by multiply)
a= 27

-6n - 14 = 18 + 10n
-16n = 32
n = -2
2/3a + 9 = 1/3a + 18
If this means (2/3)a + 9 = (1/3)a + 18 then
(1/3)a = 9
a = 27
If this means 2/(3a) + 9 = 1/(3a) + 18 then
1/(3a) = 9
1 = 27a
a = 1/27

whilst there's a huge decision in front of the parentheses, it gets better via each and every of the words interior the parentheses. So, observing the 1st difficulty, the two this is in front of the (5x - 7) gets better via each and every term. So 2 situations 5x is 10x and 2 situations 7 is 14. So the hot expression is 3x + 10x - 14. Now combine the like words. 3x plus 10x is 13x. So the respond is 13x + 14. it fairly is declared as the distributive assets because of the fact the two have been given "allotted" to the 5x and the 7. For the 2d difficulty, distribute the 4 in front of the parentheses to the 6n and the 9. 4 situations 6n is 24n and four situations 9 is 36. so which you have 24n + 36 -10n. Now, combine the like words. 24n - 10n is 14n. So the respond is 14n + 36. comparable concept with the 0.33 difficulty: distribute the 4 to the words interior the parentheses. 4 situations 11 is 40 4 and four situations -2x is -8x. so which you have 8 + 9x + 40 4 - 8x. combine the 8 and 40 4 to get fifty two; combine the 9x and the -8x to get 1x (or in simple terms x). so which you have fifty two + x. wish this facilitates! you need to ask to talk on your instructor a million on a million in case you're nonetheless having issues after she or he tries to describe it. wish that facilitates.

The first one is -2.
The second one is 27...I think. Let me think it over.
2/3a + 9 = 1/3a + 18
- 9 - 9
2/3a = 1/3a + 9
-1/3a -1/3a
1/3a = 9
x3 x3
a = 27

- 16 n = 32
n = - 2
(2 / 3) a + 9 = (1 / 3) a + 18
2a + 27 = a + 54
a = 27
