Solving Linear Equations: A Comprehensive Guide for SEO

Linear equations are fundamental in mathematics and play a significant role in various fields such as physics, economics, and engineering. This article aims to guide you through the process of solving a system of linear equations using the substitution and elimination methods. We'll use the specific example of the equations y 3x - 5 and x - y -6 to illustrate these methods. By the end of this article, you'll understand how to solve similar systems of equations and optimize your SEO content.

Solving the System of Equations

To solve the system of linear equations:

y 3x - 5 (Equation 1)

x - y -6 (Equation 2)

Step 1: Using the Substitution Method

Let's begin with the substitution method.

From Equation 1, express y in terms of x: yparl; y 3x - 5 (Equation 1)

Substitute this expression for y into Equation 2:

x - (3x - 5) -6

Now simplify and solve for x: yparl; x - 3x 5 -6 -2x 5 -6 -2x -11 x frac{11}{2} 5.5 (Equation 3)

Now substitute the value of x back into Equation 1 to find y: yparl; y 3(5.5) - 5 y 16.5 - 5 y 11.5

The solution to the system of equations is x 5.5 and y 11.5.

Step 2: Using the Elimination Method

Write down the equations again:

y 3x - 5 (Equation 1) x - y -6 (Equation 2)

From Equation 2, express x in terms of y: yparl; x y - 6 (Equation 4)

Substitute this expression for x into Equation 1:

y 3(y - 6) - 5

Now simplify and solve for y: yparl; y 3y - 18 - 5 y 3y - 23 0 2y - 23 2y 23 y 11.5 (Equation 5)

Substitute the value of y back into Equation 4 to find x: yparl; x 11.5 - 6 x 5.5

The solution to the system of equations is x 5.5 and y 11.5.
