Introduction

Linear equations are a fundamental concept in mathematics, and solving them is a crucial skill for students to master. In this article, we will explore three linear equations, labeled as Equation A, Equation B, and Equation C. Our goal is to simplify each equation, find their solutions, and then arrange them in order from least to greatest based on their solution.

Equation A: Simplifying and Solving

Equation A: $5(x-6)+3x=\frac{3}{4}(2x-8)$

To simplify Equation A, we will start by distributing the numbers outside the parentheses to the terms inside.

5(x-6)+3x=\frac{3}{4}(2x-8)

Using the distributive property, we get:

5x-30+3x=\frac{3}{4}(2x-8)

Combine like terms:

8x-30=\frac{3}{4}(2x-8)

Now, let's simplify the right-hand side of the equation by distributing $\frac{3}{4}$ to the terms inside the parentheses:

8x-30=\frac{3}{4}(2x)+\frac{3}{4}(-8)

Simplify further:

8x-30=\frac{3}{2}x-6

To isolate the variable $x$ , we will add 30 to both sides of the equation:

8x=\frac{3}{2}x+36

Subtract $\frac{3}{2}x$ from both sides:

\frac{13}{2}x=36

Finally, divide both sides by $\frac{13}{2}$ to solve for $x$ :

x=\frac{36}{\frac{13}{2}}

Simplify the fraction:

x=\frac{72}{13}

Equation B: Simplifying and Solving

Equation B: $2.7(5.1x+4.9)=3.2x+28.9$

To simplify Equation B, we will start by distributing 2.7 to the terms inside the parentheses.

2.7(5.1x+4.9)=3.2x+28.9

Using the distributive property, we get:

13.67x+13.23=3.2x+28.9

Now, let's isolate the variable $x$ by subtracting 3.2x from both sides:

10.47x+13.23=28.9

Subtract 13.23 from both sides:

10.47x=15.67

Finally, divide both sides by 10.47 to solve for $x$ :

x=\frac{15.67}{10.47}

Simplify the fraction:

x=1.5

Equation C: Simplifying and Solving

Equation C: $5(11x-18)=3(2x+7)$

To simplify Equation C, we will start by distributing 5 to the terms inside the parentheses.

5(11x-18)=3(2x+7)

Using the distributive property, we get:

55x-90=6x+21

Now, let's isolate the variable $x$ by subtracting 6x from both sides:

49x-90=21

Add 90 to both sides:

49x=111

Finally, divide both sides by 49 to solve for $x$ :

x=\frac{111}{49}

Simplify the fraction:

x=2.26530612244898

Arranging the Equations in Order from Least to Greatest

Now that we have solved all three equations, we can arrange them in order from least to greatest based on their solution.

Equation	Solution
Equation C	2.26530612244898
Equation A	5.53846153846154
Equation B	1.5

In conclusion, the correct order from least to greatest is Equation B, followed by Equation C, and then Equation A.

Conclusion

Solving linear equations is a crucial skill for students to master, and it requires a step-by-step approach. In this article, we simplified and solved three linear equations, labeled as Equation A, Equation B, and Equation C. We then arranged the equations in order from least to greatest based on their solution. By following the steps outlined in this article, students can develop a deeper understanding of linear equations and improve their problem-solving skills.
