You can put this solution on YOUR website! The Answer is : 10, 22
Start with 32. We need to have 12 greater than twice the smaller number. So we need to first subtract 12 from 32.
32-12 = 20. Then we need to divide that by two to get the smaller # 20/2 = 10
Subtract 10 from 32 to get the larger #.
32-10 = 22
Answer: 10, 22
Hope this helps! :-) Good luck!

Let the larger number be L, and the smaller S
Then L + S = 32 (their sum is 32)
Also, L = 2S + 12 (given that the larger, or L is 12 greater than twice the smaller, or S)
We now have:
L + S = 32 ------(i)
L - 2S = 12 ----- (ii)
Subtract eq (ii) from eq (i) to get: 3S = 20
Therefore, S =
Substitute this value for S in eq (i) to get:
L = or
Therefore, L, or the larger number is , while S, or the smaller number is: .

because the 22 is not 12 greater than twice the smaller
it is only 12 greater than the smaller.
32-12=20
20/3=smaller
and 40/3+12= larger
6 2/3
12 4/3=13 1/3+12=25 /13
25 1/3+6 2/3=32
check
25 1/3-12=13 1/3
13 1/3 is twice 6 2/3
ok
Answer
25 1/3
6 2/3
which is equal to maththerapy's answer since
20/3=6 2/3
76/3=25 1/3
