― Addition becomes Subtraction
― Subtraction becomes Addition
⎻ Multiplication becomes Division
⎻ Division becomes Multiplication
Solve for the Variable: Perform the inverse operation on both sides of the equation to solve for the variable.
Check the Solution: Substitute the solved value back into the original equation to ensure both sides are equal, confirming the solution’s accuracy.
By following these steps, you can systematically solve one-step equations and verify your solutions effectively.
Identifying the Operation
Identifying the operation in one-step equations is crucial for applying the correct inverse operation. Examine the equation to determine if it involves addition, subtraction, multiplication, or division. For example, in 5 + x = 10, the operation is addition, requiring subtraction to isolate x. In 7 ⎻ x = 3, subtraction is present, necessitating addition. For multiplication, as in 4 * x = 20, division is needed, while division, like in x / 3 = 9, requires multiplication. Always focus on the operation applied to the variable to choose the correct inverse operation; This step ensures clarity and accuracy in solving one-step equations effectively.
Applying Inverse Operations
Applying inverse operations is a fundamental step in solving one-step equations. For addition equations like x + 5 = 12, subtract 5 from both sides to isolate x. Similarly, for subtraction equations like x ⎻ 3 = 7, add 3 to both sides. For multiplication, such as 4x = 24, divide both sides by 4. Division equations like x / 2 = 9 require multiplication by 2. The goal is to undo the operation applied to the variable, ensuring the equation remains balanced. This systematic approach simplifies equations, making it easy to find the value of the variable.
Checking the Solution
After solving a one-step equation, it’s essential to verify the solution by plugging the value back into the original equation. This ensures accuracy and confirms that both sides of the equation are equal. For example, if you’ve solved x + 4 = 9 and found x = 5, substitute 5 into the equation to check: 5 + 4 = 9, which simplifies to 9 = 9. This validation step helps catch any mistakes and reinforces understanding. Always check your solution to guarantee it satisfies the equation.
