Math, microeconomics or criminal justice
x+x+1+x+2 = 4x-9
3x +3 = 4x-9
x =12
x+1 =13
x+2 =14
the 3 integers are 12, 13 and 14
that's probably what you want, but there is a sight ambiguity the way you wrote "4 times" the smallest number minus 9
You might have meant by that 4(x-9) if so,
3x + 3 = 4x -36 and
x = 39
x+1 = 40
x+2 = 41
the 3 numbers might be 39, 40 and 41
