23 + 21 = 44
No, 21- (5 plus 2) does NOT equal 23.
62
C+ (-2)= 21= 21+2= 23+ (-2)= 21 23+ (-2)= 21 is the same as 23- 2= 21
21
sqrt(4) + 21 = 2 + 21 = 23
23 + 10 - 12 = 21
26 - 21 = 5 or 24 - 23 = 1
7x = 21 x = 3
It is -15x2 + x - 21.
2x + 2 + 5x = 23 2x +5x = 23 -2 7x = 21 X = 3
14/21 + 9/21 = 23/21
(-18-23+20)/3= (-21)/3=-7
