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.
50 + 40 + 40 + 40 + 30 + 30 + 20 + 10 = 260
20 + 10 - 31 + 30 - 5 = 24
40+-30=10
How about: 4+10+16 = 30 as one example out of many many more possibilities
30 or -10 if the 20 is negative.

10 + 20 = 30
30
50 + 40 + 40 + 40 + 30 + 30 + 20 + 10 = 260
18 + 10 + 20 + 30 + 15 + 50= 143
-30
20 + 10 - 31 + 30 - 5 = 24
10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
40+-30=10
