15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
If 6a divided by 2 equals 12 then A equals
0.5 times 2 equals 1.
12 equals 3x(4) equals 6x(2) equals (12)x1
It is 2/3 times 12 = 8
15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
This simplifies to 6b = 12 so b = 2. Check: (9 x 2) + 7 = 25, 19 + (3 x 2) = 25 OK
The question is ambiguous because there is no sign shown before the final 6. Assume it is +6 since -6 would make factorisation very difficult. Thus the equation is 6b2 - 13b + 6 = 0 Then 6b2 - 4b - 9b + 6 = 0 or 2b(3b - 2) - 3(3b - 2) = 0 ie (3b - 2)(2b - 3) = 0 then 3b -2 = 0 or 2b - 3 = 0 so 3b =2 or 2b = 3 ie b = 2/3 or b = 3/2
If 6a divided by 2 equals 12 then A equals
(27a)2 = 729a2 (9b)3 = 729b3 So (27a)2 + (9b)3 = 729*(a2 + b3)

0.5 times 2 equals 1.
2 over 3 equals 8 over 12
2 x 6 = 12
