Answer:

20, 50

Explanation:

Let x and y represent the two numbers.

x + y = 70 . . . . . . their sum is 70

2x +10 = y . . . . . . one is 10 more than twice the other

Using the second equation to substitute for y in the first equation, we have ...

x + (2x +10) = 70

3x = 60 . . . . . . . . . subtract 10

x = 20 . . . . . . . . . divide by 3

y = 70 -20 = 50 . . . find the other number

The two numbers are 20 and 50.
