## Understanding and Solving First-Degree Equations

First-degree equations are a type of mathematical problem where we seek to find the value of an unknown, usually denoted as x. These equations are in the form ax + b = cx + d, where a, b, c, and d are known numbers.

Steps to solve the equation:

1. Group the terms with x: Move all terms containing x to one side of the equation and the constant terms to the other side. For example, in 3x + 4 = 5x + 2, we move 5x to the left and 4 to the right to get 3x - 5x = 2 - 4.
2. Simplify the equation: Combine similar terms. In our example, this results in -2x = -2.
3. Find the value of x: Divide each side of the equation by the coefficient in front of x. Here, dividing by -2 gives x = 1.

Examples:

• Example 1: Solve 2x + 3 = 7.
- Move 2x by itself to one side: 2x = 7 - 3.
- Simplify: 2x = 4.
- Divide by 2: x = 2.
• Example 2: Solve 5x + 6 = 3x + 10.
- Group terms with x: 5x - 3x = 10 - 6.
- Simplify: 2x = 4.
- Divide by 2: x = 2.

By following these steps, you can solve any first-degree equation! Don't forget to check your answer by substituting it back into the original equation.
