Hi, 

two numbers: one of the number is ten more than the other?

Let x represent one of the numbers, (n+10) the other

Write as we Read

2n + 3(n+10) = [(n+10) - n] + 20

solving for n

2n + 3n + 30 = 30

n = 0

(0+30)= 30

0 and 30 are the numbers



one of the numbers is twice as much as the other

Let x represent one of the numbers, 2x the other



2x + 3*2x = x +20

7x = 20

x = 20/7

20/7 and 40/7 are the two numbers
