Before we start sticking a bunch of x's in these things, let's remember what they are.
Look at a few examples:
| 5 | = 5
| 0 | = 0
| -3 | = 3
So...
What do absolute values do to positive numbers?

It is an example of a reflection. Line “l” would be the line of reflection. The shapes are flipped over the line, resulting in opposite orientations. This means shape A/B are the mirror-images of each other.
The answer of this question is $2.51
Let x represent the weight of a large box, and y represent the weight of a small box. The problem statement gives rise to two equations in these unknowns:
.. 12x +2y = 253
.. 3x +5y = 133
A graph shows these equations have solution
.. x = 18.5
.. y = 15.5
A large box weighs 18.5 kg.
A small box weighs 15.5 kg.
