First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.

Answer:
C and D are same options
(D)
Step-by-step explanation:

Quadratic equations are equation that has degree of 3. The value of x from the quadratic equation is 3
<h3>Factorizing the quadratic equation</h3>
Quadratic equations are equation that has degree of 3. Given the following equation;
5x²-11x = 1
Equate to zero
5x²-11x - 1 = 0
Find the solution using quadratic solution

Hence the value of x from the quadratic equation is 3
