Let the 3 consecutive integers be n-1,n,n+1.
Now 2(n+1) = 3(n-1) - 3, ie., 3n = 6 + 2n +2, ie., n = 8.
Then numbers are 7,8,9.
Integers are x , x + 1 , x + 2
2 ( x + 2 ) = 3x - 3
2x + 4 = 3x - 3
7 = x
Integers are 7 , 8 , 9
7, 8 and 9 are the three consecutive integers as required.
Three consecutive integers such that, 2(x + 1) = 3(x - 1) - 3 ,
twice the greatest integer is 3 less than 3 times the least integer:
7, 8, and 9.
n – 1, n, n + 1
2(n + 1) = 3(n – 1) - 3
2n + 2 = 3n – 6
Middle number n was 8, so, 7, 8, 9
Three consecutive integers:
x, (x + 1), (x + 2)
Twice the greatest integer is 3 less than 3 times the least integer
2(x + 2) = 3x - 3
x = 7
x + 1 = 8
x + 2 = 9
ANS 7, 8 and 9
Check:
2 x 9 = 18
3 x 7 = 21
21 - 3 = 18
Three consecutive integers.
I'll call the middle number "x", so the one before and after it are: (x - 1) and (x + 1)
Twice the greatest: 2(x + 1)
is 3 less than 3 times the least: 3(x - 1) - 3
Set them equal and solve for x:
2(x + 1) = 3(x - 1) - 2
2x + 2 = 3x - 3 - 2
2x + 2 = 3x - 5
-x = -7
Remember that I called "x" your middle number, so your three numbers are:
6, 7, and 8
