The sum of three numbers is 110

Question

The sum of 3 numbers is 110. The third number is 4 times the second. The second number is 10 more than the first. What are the numbers?

Answer 1

Let x, y, & z be the 3 numbers. Based on the information given

x+y+z = 110

z = 4y

y= x+10 substituting into the first equation

x + x + 10 +4(x+10) = 110

or 6x = 60

then x = 10

y = 20

z = 80
