Answer:
Number of stickers Sarah had = 28
Number of stickers she put on her binder = x.
Number of stickers left with her = 28 - x
Number of stickers Haylee had = 40
Number of stickers she put on her locker = 3x
Number of stickers left with her = 40 - 3x
Both Sarah and Haylee had the same number of stickers left.
28 - x = 40 - 3x
=> 3x - x = 40 - 28
=> 2x = 12
=> x = = 6

Answer:
x=-14 and y = 9
Step-by-step explanation:
hello
4x + 8y = 8 <=> divide by 4 both parts
(1) x + 2y = 4
(2) x + 3y = 13
(2) - (1) gives
x + 3y -x - 2y = 13 - 4 = 9
<=> y = 9
we replace in (1) x + 2*9 = 4
<=> x = 4 - 18 = -14
so x = -14
hope this helps
