45 and 5
15 and 36
40 and 10
20 and 30

Answer 1

There are two unknowns in the problem statement above so we need two equations in order to solve this. The firs expression is that the sum of two numbers is 50.

x + y = 50

The second expression is that the one number is 10 less than three times the other number.

x = 10 - 3y

Therefore, the two numbers have values 40 and 10. Hope this answers the question. Have a nice day.
