10 + 12/3 + 20 = 34
20/10 + 10 = 12 20/(10 + 10) = 1
10 plus 10 equals 20 20 divide by 10 equals 2 2 plus 10 equals 12
2 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 106
-5 + (-4) - 12 - 20 - (-10) + 6 = -25
-12
20 + 12 + 32 + 20 + 30 + 72 = 186
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.
20 + 50 + 20 + 10 = 50 = 150
-22
30 or -10 if the 20 is negative.
7 + 5 = 12 = 10 + 2 20 + 20 + 10 = 50 2 + 50 = 52
