Step-by-step explanation:
Mathematically speaking, the statement is equivalent to this 2-variable non-linear system:
First, is cleared in the first equation:
Now, the variable is substituted in the second one:
And some algebra is done in order to simplify the expression:
Roots are found by means of the General Equation for Second-Order Polynomials:
and
There are two different values for :
There are two possibilities:
and
and
For this case we have the following expression:
By definition, a coefficient is the term that accompanies one or more variables.
For example:
The coefficient of the linear term is 3.
So, in the given expression we have to:
-4 is the term that accompanies the variables xy.
Answer:
-4
