Solving Equations with Variables: A Comprehensive Guide

Mathematics is a fundamental subject that underpins numerous areas of study and practical applications. Understanding how to solve equations with variables, such as 5x 3 1 - 17, is a crucial skill. This article will walk you through the process of solving these types of equations step-by-step, providing clear explanations and examples.

Solving the Equation 5x 3 1 - 17

Let's begin with the equation 5x 3 1 - 17. The goal is to isolate the variable x on one side of the equation. Here's a detailed breakdown of the steps:

Rearrange the equation to isolate the term with the variable. Start by simplifying the right side of the equation: 5x 3 1 - 17 Simplify the right side. Combine the constants on the right side: 5x 3 -16 Isolate the term with the variable. Subtract 3 from both sides to move the constant to the right side: 5x -19 Solve for x. Divide both sides by 5 to isolate x: x -19 / 5 Calculate the value of x. Perform the division: x -3.8

So, the value of x is -3.8.

Additional Examples

Example 1: 5x - 3 1 - 17

Let's solve another equation to solidify your understanding:

Rearrange the equation. Simplify the right side: 5x - 3 -16 Isolate the term with the variable. Add 3 to both sides: 5x -13 Solve for x. Divide both sides by 5: x -13 / 5 Calculate the value of x. Perform the division: x -2.6

Example 2: x - 3x -10 - 5

Another common form of equation involves combining like terms:

Simplify the left side. Combine the terms involving x on the left side: -2x -15 Solve for x. Divide both sides by -2: x 15 / 2 Calculate the value of x. Perform the division: x 7.5

Conclusion
