Answer:
A
Step-by-step explanation:
x² - 10x + 18 = 0
x² - 2(x)(5) + 5² - 5² + 18 = 0
(x - 5)² = 7
x = 5 + sqrt(7), 5 - sqrt(7)
sqrt: square root
On solving the linear system, for the value of y = 15, the value of x is 200. The correct option is D.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The linear equation is shown below.

The equation can be written as

For y = 15, the value of x will be.

The value of x is 200.
Thus, option D is correct.
