Question

# Find the solution of the system of equations.

y = 5 - 2x

Hint:

### The expansion of the identity (x + a)^{2} = x^{2} + 2ax + a^{2}. A polynomial of degree two 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 is equal. Thus, equate the RHS of the equation.

Step 2 of 3:

Solve the solution for the variable x:

The multiplicity of the value is two.

Step 3 of 3 :

Substitute the value of in any of the equation to get the value of y,

when x = -5,

Thus, the solution of the set of equation is (-5, 15).

The multiplicity of a value is the number of time is repeat itself.
