The sum of two numbers is 50. One number is 10 less than three times the other number. What are the two numbrs

  15, 35

Step-by-step explanation:

Let x represent the smaller number. Then the larger is 3x-10, ten less than 3 times the smaller. Their total is ...

  x + (3x -10) = 50

  4x = 60 . . . . . . . . add 10

  x = 15 . . . . . . . . . .divide by 4

  50 -15 = 35

The two numbers are 15 and 35.
