a = 20
20 + 6 - 56 = -30

I am having difficulty understanding your question. 12 + 20 = 10 is obviously false (12 + 20 = 32).If 4x + 14 = 2x + 30, then x must equal 8.
132

a = 20
10
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
18 + 10 + 20 + 30 + 15 + 50= 143
20 + 6 - 56 = -30

To solve this one, subtract 50 from 180 and you'll have your answer.
The total is 400.
No, 10% + 20% = 0.3 or 30%
-8x - 10 - 20 = -8x - 30
