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
12 equals 3x(4) equals 6x(2) equals (12)x1
Oh, dude, that's like basic math, but I got you! So, to find out what number times 12 equals 144, you just divide 144 by 12. And guess what? The answer is 12! It's like 12 times 12 equals 144. Mind-blowing, right?
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
