Question

what algebraic equation represents "three times the differece of a number,x, and nine equals fifteen

Answer 1

3(x - 9) = 15

Answer 2

3(x-9) = 15

Answer 3

3(x - 9) = 15

Answer 4

the difference of x and 9 is 9-x if x is less than 9, and
x-9 if x is bigger than 9

so we want 3 times the difference

3(9-x)

and this equals 15

3(9-x) = 15

and if x is bigger than 9 we have

3(x-9) = 15

Answer 5

3 (x-9) = 15

Answer 6

@eigenschmeigen is correct

Answer 7

3 |x-9|=15
