Final answer:

The y-coordinate of the solution depends on the value of x in the given system of equations. If x = (6 - √84) / 2, the y-coordinate is 11 * ((6 - √84) / 2)

Step-by-step explanation:

The given system of equations is y = 11x and 3y = x^2 + 5x + 12. Since the system has one solution, we can set the two equations equal to each other:

11x = x^2 + 5x + 12

Rearranging the equation, we get:

x^2 - 6x - 12 = 0

To find the x-coordinate of the solution, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

Plugging in the values from the equation, we get:

x = (-(-6) ± √((-6)^2 - 4(1)(-12))) / (2(1))

Simplifying, we have:

x = (6 ± √(36 + 48)) / 2

x = (6 ± √84) / 2

Now, we can calculate the two possible y-coordinates by substituting the x-values into one of the original equations:

For x = (6 + √84) / 2: y = 11 * ((6 + √84) / 2)

For x = (6 - √84) / 2: y = 11 * ((6 - √84) / 2)

Therefore, the y-coordinate of the solution depends on the value of x:

If x = (6 + √84) / 2, the y-coordinate is 11 * ((6 + √84) / 2)

If x = (6 - √84) / 2, the y-coordinate is 11 * ((6 - √84) / 2)
