For this case we have that by definition, a function is of the form:

So, we have the following system of equations:

Equating the equations we have:

Adding 2x to both sides of the equation:

Subtracting 2 from both sides of the equation:

Dividing between -4 on both sides of the equation:

Thus, the value of the variable "x" is -0.5.
Answer:
