Question

The sum of three numbers is 160. The third number is 4 times the second. The first number is 10 more than the second. What are the numbers?​

Answer 1

160 = (10 + x) + x + 4x
160 = 6x + 10
150 = 6x
150/6 = x
x = 25

second number = x = 25
third number = 4x = 100
first number = x + 10 = 35
