Answer:
<em>Standard form: </em><em></em>
<em>A = 12, B = 3 and C = -2</em>
<em></em>
Step-by-step explanation:
Given:
The equation:
To find:
The standard form of given equation and find A, B and C.
Solution:
First of all, let us write the standard form of an equation.
Standard form of an equation is represented as:
A is the coefficient of x and can be positive or negative.
B is the coefficient of y and can be positive or negative.
C can also be positive or negative.
Now, let us consider the given equation:
Multiplying the whole equation with 3 first:
Now, let us take all the terms on one side:
Now, let us compare with .
So, <em>A = 12, B = 3 and C = -2</em>
