Answer:

Whitney made 6 baskets

Step-by-step explanation:

Let the number of baskets made by Whitney be x.

The 15 baskets made by

Chiyann is equal to 2 times plus 3 what Whitney made

Mathematically what she made would be 2x + 3

To get x, we equate this equation to 15

2x + 3 = 15

2x = 12

x = 12/2

x = 6 baskets

-(x + 2) - 2x = -2( x + 1)

$-(x+2)-2x=-2(x+1)\\\\-x-2-2x=-2x-2\\\\-3x-2=-2x-2\ \ \ \ \ \ |add\ 2\ to\ both\ sides\\\\-3x=-2x\ \ \ \ \ \ \ \ |add\ 2x\ to\ both\ sides\\\\-x=0\\\\\boxed{x=0}$
