Question 93861
The sum of two numbers is 43. The second is 1 more than 2 times the first. What are the two numbers? 
------------------
x+y=43
y = 2x+1
------------
Substitute the 2nd into the 1st to get:
x + 2x+1 = 43
3x = 42
x = 14
-------------
Substitute that into y=2x+1 to solve for y:
y = 2*14+1
y = 29
==============
The numbers are 14 and 29
