Question

# Find the solution of the system of equations.

Hint:

### The expansion of the identity . A polynomial of degree has at most two real solutions.

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 the same. Hence, equate them to eliminate a variable. Thus, we get:

We factorized seven out of the equation to simplify it.

step 2 of 3

Now, solve the simplified equation:

Here, the multiplicity of the solution is two.

Step 3 of 3

Substitute the found value of in any of the equation, to find the value of Y.

when x = 1,

Thus, the solution is (1,19).

The multiplicity of a solution is the number of times that value appears to be a solution of an equation.
