How can x2 = 2x + 4 be set up as a system of equations?
\(\bf x^2=2x+4\implies \begin{cases} y=x^2 \\\\ y=2x+4 \end{cases}\implies y=y\)
Answer:
Thus, our system of equation becomes,
\(x^2-y=0\) and \(y-2x=4\)
Step-by-step explanation:
Given equation : \(x^2=2x+4\)
We have to set up the given equation as a system of equations.
We can set an equation as a system of equations by placing its both side equal to a single variable term.
Consider the given equation \(x^2=2x+4\).
since, the given equation \(x^2=2x+4\) has two sides right side and left side , let put them equal to a same variable y ,
then we get,
\(x^2=y\) and \(2x+4=y\)
Thus, our system of equation becomes,
\(x^2-y=0\) and \(y-2x=4\)
