Answer:
x=5
Explanation:
(Not sure how I was supposed to do the model..so I ended up doing it this way..)
3x-5=10
Add 5 on both sides and then you get
3x=15
divide both sides by 3 and then you get
x=5
(Hopefully you can see my model even if it's just a little...)
For the model I drew 3 rectangles and put an x inside each one of them. for the -5, I drew 5 squares with a minus symbol/sign inside. And then I put an equal sign beside and I drew 10 squares with nothing inside but you can draw positive signs in it to show that it's positive..
So basically mines was
3 rectangles with x inside -5 squares with - inside = 10 squares
