L = larger number
S = smaller number
L = S + 12
S + 2L = 39
S + 2(S+12) = 39
S +2S + 24 = 39
3S + 24 = 39
3S = 15
S = 5
L = 17
5 + 34 = 39

call the small volume x, and the tremendous volume y. Then all of us recognize correct right here: x+12 = y x+2y = 39 that is a gadget of equations which will be solved in diverse strategies. A nifty way is to operate 2y to the first equation: x + 2y+12 = 3y <=> 39+12 = 3y <=> 51 = 3y or y = 17. for this reason, x=5.

the equation of the exercise is : a+2b=39
a-b=12
a=12+b
12+b+2b=39
3b=27
b=9
a=21 21 is the larger number
