Let x and y be the two numbers.

Their sum is 140, so

x + y = 140

Twice the first number x is 2x. 5 more than this is 2x + 5. This is the value of the second number, so

y = 2x + 5

Substitute this into the first equation and solve for x :

x + (2x + 5) = 140

3x + 5 = 140

3x = 135

x = 135/3 = 45

Then

y = 2*45 + 5 = 95
