Which system of equations can be graphed to find the solution (s) to 4x2 = x2 - 7?

You dnon't need to graph a nutty system of equations

hmm

4x^2=x^2-7

minus x^2

3x^2=-7

divide both sides by 3

x^2=-7/3

false unless you want complex roots

one way is to graph the lines

y=4x^2

y=x^2-7

find where they intersect (they don't on the real plane)
