You can put this solution on YOUR website! If the sum of two consecutive numbers is 9. If two times the 1st number less than 3 times the 2nd number is 7. what are the two numbers?
-------------------
If the sum of two consecutive numbers is 9
1st: x
2nd: x+1
EQUATION:
x + x+1 = 9
-----------------
2x + 1 = 9
x = 4 ; x+1 = 5
============================
If two times the 1st number less than 3 times the 2nd number is 7.
2x - 3(x+1) = 7
-x = 8
x = -8; so x+1 = -7
=========================
