One number is one more than another. their sum is fifteen. find both numbers.

the smaller number is __ and the larger number is

The answer to your question is:  7 and 8

Step-by-step explanation:

One number = n

one more than another = n + 1

Their sum           n + n + 1 = 15

                          2n = 15 - 1

                         2n = 14

                         n = 14/2

                         n = 7

                         n + 1 = 8

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
