#1 #2 #3
Take the first number the second is 6 Whatever the 2nd
multiply it by 10 and more than the first is, you have to
add 12 to it to get so we have to find out multiply it by 7.
the 3rd number. what the 1st# is.
You don't have enough Information. You need to have a hint for how to find the first number.

Ok. Let's put that into equations...
Let's call the numbers A, B, and C
B = A + 6
C = 7 * B
C = 12 + 10 * A
Now let's combine some equations to remove some variables.
C = 7*B
C = 7*(A+6)
C = 7*A + 42
From earlier, we have, C = 10*A + 12
If we subtract one from the other we
(C-C) = 10*A-7*A+12-42
0 = 3*A - 30
30 = 3*A
10 = A
Now plug that into the other equations...
B = A + 6
B = 10 + 6
B = 16
C = 12 + 10*A
C = 12 + 10*10
C = 12 + 100
C = 112
So, A = 10, B = 16, C = 112
