The sum of three numbers is 95. The first number is 7 less than the second. The third number is 4 times the second. What are the numbers? First? Second ? And Third?

10, 17, 68

Step-by-step explanation:

95 = (x - 7) + x + 4x

combine like terms

95 = 6x - 7

95 + 7 = 6x

102 = 6x

x = 102/6

x = 17

17 - 7 = 10

4 x 17 = 68
