x/2 = 21 x = 42
273 13+8 = 21 and 13*21 = 273
C+ (-2)= 21= 21+2= 23+ (-2)= 21 23+ (-2)= 21 is the same as 23- 2= 21

5 plus 25 equals 60. Need to solve for 5 plus 25 equals ?: 2 plus 10 equals 24 is equivalent to 2 × (1 plus 5) equals 2 × (12); and 3 plus 15 equals 36 is equivalent to 3 ×(1 plus 5) equals 3 × (12); thus 5 plus 25 equals ? is equivalent to 5 × (1 plus 5) equals 5 × (12); thus ? = 5 × 12 = 60.
273 13+8 = 21 and 13*21 = 273
7 + 21 + 2 + 86 + 4 = 120
It equals 70
I x=5 and y=2, then (5x5)=25 plus (9x2)=18. 25+18=43
C+ (-2)= 21= 21+2= 23+ (-2)= 21 23+ (-2)= 21 is the same as 23- 2= 21
few errors in your title: 2 plus 4 = 6 6 plus 9 = 15 10 plus 25 = 35 18 + 81 = 99

26 - 21 = 5 or 24 - 23 = 1
25 + 2 = 27 27 - 19 = 8
