This system has one solution. {y=−2x+4y {=x2+4x+13 what is the y-coordinate of the solution? enter your answer in the box. y =[]

The y-coordinate of the solution is, 10

Step-by-step explanation:

Given the system of equation:

           ....[1]

        ....[2]

Equate the equation [1] and [2] we have;

Add 2x to both sides of an equation:

Subtract 4 from both sides we have;

or

Using perfect square:

⇒We can write the equation as:

then;

⇒

Subtract 3 from both sides we have;

x = -3

Substitute value of x in [1] we have;

⇒

Solution for the given system of equation = (-3, 10)

Therefore, the  y-coordinate of the solution is, 10
