1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 = 210

24 + 23 + 22 + 21 + 20 + 19 + 18 + 17 + 16 + 15 + 14 + 13 + 12 + 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 300
-4x + 5 + 3x + 6 = -x + 11
Nine plus two equals 11 and when you add six to 11 you get 17.
x=-6
q=-6
7x-11=-19+3x 4x=-19+11 4x=-8 x=-2 Check it 7x(-2)-11=-14-11=-25 And -19+(-2)x3=-19-6=-25 It works.
18 + 11 + 6 + 19 = 54
The pattern is this: The number before, plus itself plus 2. For example: 1 (number)+ 0 (number berfore)+ 2 (always use a two in this pattern) = 3 then 1+3+2=6 then 3+6+2+11 and 6+11+2=19, which is your pattern. So the answer is 11+19+2=32. Now the pattern is 1,3,6,11,19,32 Thats a wrap.
19 and 5 over 6
-25
-19 + 6 - 25 = -38
It is: 6+80-19 = 67
(5-8)+(1-11) 5-8+1-11 6-19 -13
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 = 210
7X - 11 = - 19 + 3Xsubtract 3X from both sides4X - 11 = - 19add 11 to both sides4X = - 8divide both sides integers by 4X = - 2=====----------- check in original equation7(- 2) - 11 = - 19 + 3(- 2)- 14 - 11 = - 19 - 6- 25 = - 25==========checks
