Question

# Find the solution of the system of equations.

Y= 2x

Hint:

### A quadratic equation of the form can be simplified into . This can be further solved by equating it to zero.

We are asked to solve the set of equation.

## The correct answer is: We are asked to solve the set of equation.

### Step 1 of 3:

The LHS of the given set of equation is equal. Hence, we can equate them:

Step 2 of 3:

Solve the equation for the variable x:

Step 3 of 3:

Now, substitute the values of x in any of the equation, to get values of y:

When x=1,

When x=-2,

Thus, the solutions of the set are: (1, 2) and (-2, -4)

A quadratic equation can have a maximum of two real roots. There are instances where it has no real roots.
