The difference of a number and 9 is the same as 47 less the number. Find the number

n = 28

Step-by-step explanation:

Let n - the number

The difference of a number and 9 is the same as 47 less the number.

n - 9 = 47 - n add 9 to both sides

n - 9 + 9 = 47 + 9 - n

n = 56 - n add n to both sides

n + n = 56 - n + n

2n = 56 divide both sides by 2

2n/2 = 56/2

n = 28
