Using three consecutive integers,
x, (x+1), (x+2)
such that
if three times the first is subtracted from the five times the third,
the difference equals eight.
5(x+2) - 3x = 8
5x + 10 - 3x = 8
5x - 3x = 8 - 10
2x = -2
x = -1
:
Find the second integer.
Add 1 to get the next integer, -1 + 1 = 0 is the 2nd integer

Check this in the original equation for x = -1
5(-1+2) - 3(-1) = 8
5(1) + 3 = 8
