In a basketball game, benito scored 3 points less than twice the number of points carnell scores. cornell scored eight points. how many points did benito score?

Benito scored 5 points

For this questions we would have to make an equation to solve for x. But my brain isn't not working so I'm just going to solve it the easy way. The equation would be:
(2 x 8) - 3 = ?
16 - 3 = 13
13 = number of points scored by Benito.
2 times 8 would be two even the amount of points Carnell scored. Then we subtract 3 because Benito scored 3 less than that amount. This would leave us with 13 points scored for Benito.

I’m confused what’s happening
