<span> x – 3y = 9 ------------ (1)
1/5x - 2y = -1---------- (2)
(1):
x - 3y = 9
x = 9 + 3y ----------- (1a)
(2):
</span>1/5x - 2y = -1
x - 10y = -5 --------- (2a)
Sub (1a) into (2a):
9 + 3y - 10y = -5
9 - 7y = -5
-7y = -5 - 9
-7y = -14
7y = 14
y = 2 ---------- Sub into (1a)
x = 9 + 3y
x = 9 + 3(2)
x = 9 + 6
x = 15
Ans: x = 15, y = 2

Find the volume of each and then divide the volume of the box by the volume of the cube.
Volume of box: 8 1/2 x 5 1/2 x 2 1/2 = 116 7/8 cubic inches.
Volume of cube = 1/2^3 = 1/8 cubic inches
Number of cubes: 116 7/8 / 1/8 = 935 cubes.
