5 0

The easy thing to do is eliminate x by subtraction

x + 7y = 24
- x - 9y = -24
-------------------
16y = 48

now solve for y and then substitute the value into either original equation to find x

24 2

12 2

6 2

3 3

2.- Volume of a rectangular package

Volume = length x height x width

3.- Possible values are, combine the prime factors to find the volume

Volume = 4 x 2 x 3 or

Volume = 2 x 4 x 3

Volume = 3 x 2 x 4

Volume = 2 x 2 x 6

Volume = 6 x 2 x 2

Volume = 2 x 6 x 2

Volume = 12 x 2 x 1

Volume = 1 x 12 x 2

Volume = 2 x 1 x 12
