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 how to solve linear equations, with a focus on the general form of the equation and how to use it to solve specific equations. We will also examine a real-world example of solving a linear equation, using the general form to find the solution.

The General Form of a Linear Equation

A linear equation is an equation in which the highest power of the variable (in this case, mm) is 1. The general form of a linear equation is:

ax=bax = b

where aa and bb are constants, and xx is the variable. However, when the equation is solved for xx, the general form becomes:

x=bax = \frac{b}{a}

This is the form that Nathaniel uses to solve the equation $-3 m = 4 m - 15$ for mm.

Solving the Equation for mm

To solve the equation $-3 m = 4 m - 15$ for mm, Nathaniel uses the general form of the equation. He first isolates the variable mm on one side of the equation by adding 3m3m to both sides:

−3m+3m=4m−15+3m-3 m + 3 m = 4 m - 15 + 3 m

This simplifies to:

0=7m−150 = 7 m - 15

Next, Nathaniel adds 15 to both sides of the equation to isolate the term with the variable:

0+15=7m−15+150 + 15 = 7 m - 15 + 15

This simplifies to:

15=7m15 = 7 m

Finally, Nathaniel divides both sides of the equation by 7 to solve for mm:

157=7m7\frac{15}{7} = \frac{7 m}{7}

This simplifies to:

m=157m = \frac{15}{7}

Q: How do I isolate the variable on one side of the equation?

A: To isolate the variable on one side of the equation, follow these steps:

  1. Add or subtract the same value to both sides of the equation to eliminate any constants on the same side as the variable.
  2. Multiply or divide both sides of the equation by the same value to eliminate any fractions or decimals on the same side as the variable.

Q: What is the difference between a linear equation and a quadratic equation?

A: A linear equation is an equation in which the highest power of the variable (in this case, mm) is 1. A quadratic equation is an equation in which the highest power of the variable (in this case, mm) is 2. For example:

Linear equation: 2m=52m = 5 Quadratic equation: m2+3m+2=0m^2 + 3m + 2 = 0

Q: Can I use a calculator to solve a linear equation?

  • Failing to isolate the variable on one side of the equation.
  • Not using the general form of the equation to solve for the variable.
  • Not checking the solution by plugging it back into the original equation.

Q: How do I check my solution to a linear equation?

A: To check your solution to a linear equation, plug it back into the original equation and make sure it's true. For example, if you solve the equation 2m=52m = 5 and get m=2.5m = 2.5, plug m=2.5m = 2.5 back into the original equation to make sure it's true:

2(2.5)=52(2.5) = 5 5=55 = 5

Since the equation is true, your solution is correct.
