one number is 5 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 422, find the numbers.

Answer 1

S=5F

T = 100+F

F+S+T = 422

F +5F + 100+F = 422

7F = 422-100 = 322

F = 322/7 = 46 = the First number

S=5x46 = 230 = the Second number

T = 46+100= 146 = Third number

46+230+146 = 422
