One number is 14 more than another. The sum of the two numbers is 20. Find the numbers.

Question

campbell_st · Answer

so let x be the 1st number, 

then the 2nd number is x + 14

so now you can set up an equation to solve 

x + x + 14 = 20

just collect like terms then solve for x.

Thanks @campbell_st!
So, just to clarify, I would insert two different random numbers (reasonable ones) in place of the x's?
