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

See explanation

Step-by-step explanation:

To solve the equation graphically, we need to consider left and right parts of this equation separately.

Left side gives us the function The graph of this function is shown with green curve in attached diagram.

Right side gives us the function The graph of this function is shown with blue curve in attached diagram.

The x-coordinates of the points of their intersections are the solutions to the equation

From the graph you can see that the solutions are

168

step-by-step explanation:

i am pretty sure that the answer is 168
