the number is one

work:

let's analyze the question.

15 times a number is..

so, right away we have 15n.

.... decreased by eight...

we are subtracting 8, so 15n - 8

...the result is 17.

so, 15n - 8 will equal 17.

Find the number.

now, we solve for n.

15n - 8 = 17 (add 8 to both sides)

15n = 15 (divide both sides by 15)

n = 1

so, the number is one. hope this helps, have a great day!
