x = 11, y = 3 and z = 55

Step-by-step explanation:

Let the three numbers be x, y and z.  Then x + y + z = 69

Then y = x - 8, and z = 5x.  Substituting these expressions in x into

x + y + z = 69, we get:  x + x - 8 + 5x = 69, or

7x = 77, so that x = 11.

If x = 11, then:

y = x - 8 = 11 - 8 = 3, and:

z = 5x = 5(11) = 55

Then x = 11, y = 3 and z = 55.

Check:  Do these three numbers add up to 69?  11 + 3 + 55 = 69?  YES
