9 plus 11 (20) plus 15 (35) plus 18 is equal to 53
10 plus 20-2 - 11 plus 3 is equal to 20.
-110
It is: 6-11+5-8c+9c = c
17 + 14 + 17 + 19 + 18 + 13 + 11 = 109
5e + 18 ≤ 6e + 29 -11 ≤ e That is, e ≥ -11
4e + 3d + 5e - 5d = 9e - 2d
22 :)
11 + (19 + 6) = 36(11 + 19) + 6 = 36So they are both equal. The brackets make no difference in this case.
14 + 3 + 11 = 28
14 + 11 + 3 = 28
Simplified is 5e-2f.

9 plus 11 (20) plus 15 (35) plus 18 is equal to 53
10 plus 20-2 - 11 plus 3 is equal to 20.
It is: -5+10+11-4 = 12
