Nine is subtracted from seven times some number and the result is the sum of the number and 3?

Answer 1

7n - 9 = n + 3

Answer 2

Hi Tami!

Let's call 'some number' as the variable x.

9 is subtracted from 7 times x and that is equal to the sum of x + 3

9 - 7x = x + 3

Solving this out, you would get like terms on either side.

-8x = -6 OR 8x = 6 (either one works)

x = 6/8 or 3/4 (0.75)

Hope this helps!
