X-5/3 =1
Or
X - 5 = 1
______
3
I'm trying to type and tell you it's x-5 over 3 equals 1

I don't know how to do
I think I have to do reverse operation which is multiply

• algebra -

(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.

Ok. I get it know
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
