Step-by-step explanation:
Backpack 2 is 2x, 2y, so double each number:
(0,2) = (0, 4)
(8,2) = (16, 4)
(6,5) = (12, 10)
(2,5) = (4, 10)
(0,2) = (0,4)
Backpack 3 is x + 8, y - 2 so add 8 to x and subtract 2 from y:
(0,2) = (8, 0)
(8,2) = (16, 0)
(6,5) = (14, 3)
(2,5) = (10, 3)
Backpack 4 is x, 2y, so keep the same x and multiply y * 2
(8,2) = (8, 4)
(6,5) = (6, 10)
(2,5) = (2, 10)

I hope this helps you
4x - 3 = 25
+ 3 + 3
4x = 28
x = 7
