H2 Heading: Understanding Systems of Linear Equations with Two Unknowns
In this article, we will delve into the concept of solving systems of linear equations with two unknowns. We will explore various scenarios and uncover the number of solutions for each system. By the end of this article, you will have a solid understanding of this fundamental mathematical concept.
H3 Heading: Exploring Different Systems of Linear Equations
Let’s examine different scenarios and solve the following systems of linear equations:
a)
Consider the system:
(d): y = -2x + 3, with a = -2 and b = 3
(d’): y = 3x – 1, with a’ = 3 and b’ = -1
Since a ≠ a’, the lines (d) and (d’) intersect, resulting in a unique solution for the system.
b)
Consider the system:
(d): with a = ; b = 3
(d’): with a’ = ; b’ = 1
Since a = a’ and b ≠ b’, the lines (d) and (d’) are parallel, meaning the system has no solution.
c)
Let’s examine the system:
(d): y = x, with a = ; b = 0
(d’): y = x, with a’ = ; b’ = 0
Since a ≠ a’, the lines (d) and (d’) intersect, leading to a unique solution for the system.
d)
Now, let’s consider the system:
(d): with a = a’ = 3 and b = b’ = -3
We observe that the two lines overlap, indicating that the system of equations has an infinite number of solutions.
