Answer:

10, 11 and 12.

Explanation:

Let the integers be x, x+1 and x+2. Then:

x + x+2 = 22

2x = 22 - 2 = 20

x = 20/2

x = 10.

Answer:

Consecutive integers:

x

(x+1)

(x+2)

Now your equation is given by sum of the first and twice the third is equal to four times the second decreased by five:

x+2(x+2) = 4(x+1)-5
