**David Q/R**, Sunday, October 14, 2012 at 1:13pm(x-5)/3 = 1, so multiply both sides of the equation by 3, and you'll get

(x-5) = 3.

Now add 5 to both sides of the equation and you'll get

x = 3 + 5 = 8.

And that's your answer.

3/1 *x-5/3. = 1*3

Leaves

X-5 = 3

+5 = 3+5

X= 8

So next time I should do what I think which multiple. I just got thrown off cuz of x-5

Thank you
