It doesn't, it should equal 45 again. I am unsure how you got this second answer but it is wrong
21
22
x=9
63 + 20 - 60 = 23
The answer to this sum is 2010198.
26 - 21 = 5 or 24 - 23 = 1
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
Yes...506 divided by 23 equals 22 so 22 times 23 equals 506
23 plus 7684235 equals 7684258.
2a + 2b = 26 2b + c = 22 ===> b = 11 - c/2 4c + 2b = 46 ===> b = 23 - 2c From the 2nd and 3rd equations: 11 - c/2 = 23 - 2c 22 - c = 46 - 4c 22 - 46 = -4c + c ===> -24 = -3c ===> c = 8 Substitute c=8 into the 3rd equation: b = 23 - 16 = 7 Substitute b=7 into the 1st equation: 2a + 14 = 26 2a = 12 ===> a = 6
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
It equals 435
