Question

Which system of equations can be graphed to find the solutions to 4x^2=x^2-7

Answer 1

check the picture below.

Answer 2

`y=4x^2`

`y=x^2-7`

Explanation:

Since, when we solve a one variable linear equation by graphing,

We introduce a new variable 'y',

And, equate both sides of the equation by this variable ,

Here, the given equation,

`4x^2=x^2-7`,

Thus, the system of equations would be,

`y=4x^2`

`y=x^2-7`

By graphing these equations, the x-coordinate of there intersection point would be the answer.
