The first one: A=-15
Second one: B= -0.5
Third one: C= 0.01
Carbon Dioxide: o2c
Water: h2o
Oxygen: o2
Water is h2o because there are 2 hydrogen molecules and 1 oxygen molecule.
h2 = 2 hydrogen molecules
o = 1 oxygen molecule
The system of equations are:
$12p + $3a = $258
a - p = 6
Where:
- a = phone accessories
- p = phone
<h3>What are the system of equations?</h3>
Two linear equations would be derived from the question. The linear equations would be a function of the phones and accessories sold. These equations are known as simultaneous equations and they would have to be solved together in order to determine the required values.
