when 1 is subtracted from three times a certain number and then divided by 5,the result is the same as when 1 is added to the number what is the number

4 answers

x = your number

( 3 x - 1 ) / 5 = x + 1

Multiply both sides by 5

3 x - 1 = 5 x + 5

Add 1 to both sides

3 x = 5 x + 6

Subtract 5 x to both sides

- 2 x = 6

x = 6 / - 2

x = - 3
please is this the answer
Really, John???
He went through all those calculations just for you, and ends with

x = -3

and you come back with: "is this the answer?"

and you didn't even check to make sure it works?
BOOOOOOOOOOOOOOOOO!!!
given that B is directly proportional to A and B=20 when A=5, find B when A=9.
