We want to solve the given using the .
Note that neither of the variables is isolated in either equation, so we will start by isolating
in Equation (II).
variable is isolated in Equation (II). This allows us to substitute its value
in Equation (I).
Notice that in Equation (I), we have found that
We can substitute this result into Equation (II) and solve for
We found that
It means that the only solution to our system, which is the only point of intersection of the two , is
