Solving Equations with Commentary and Verification

Sure! I can help you solve equations. Please provide the equations you would like me to solve.

Note: I will be using the search results snippets to provide the solutions and commentary for each equation.

1. Equation: (300 * - 72) : 7 = 96 + 108

To solve this equation, we can follow these steps: - Simplify the left side of the equation: (300 * - 72) : 7 = 204 - Simplify the right side of the equation: 96 + 108 = 204 - Since both sides of the equation are equal, the solution is valid.

Therefore, the solution to the equation is 204. 2. Equation: 2 - 34 + 23 = 95

To solve this equation, we can follow these steps: - Simplify the left side of the equation: 2 - 34 + 23 = -9 - Simplify the right side of the equation: 95 - Since the left side is not equal to the right side, the equation does not have a valid solution.

Therefore, the equation 2 - 34 + 23 = 95 does not have a solution. 3. Equation: 93 * x = 6231

To solve this equation, we can follow these steps: - Divide both sides of the equation by 93: x = 6231 / 93 - Simplify the right side of the equation: x = 67

Therefore, the solution to the equation is x = 67. 4. Equation: x * 7 = 42

To solve this equation, we can follow these steps: - Divide both sides of the equation by 7: x = 42 / 7 - Simplify the right side of the equation: x = 6

Therefore, the solution to the equation is x = 6. 5. Equation: 36 / x = 4

To solve this equation, we can follow these steps: - Divide both sides of the equation by 4: 36 / x = 4 - Simplify the left side of the equation: 9 = x

Therefore, the solution to the equation is x = 9. 6. Equation: 9 * x = 45

To solve this equation, we can follow these steps: - Divide both sides of the equation by 9: x = 45 / 9 - Simplify the right side of the equation: x = 5

Therefore, the solution to the equation is x = 5. 7. Equation: x / 6 = 6

To solve this equation, we can follow these steps: - Multiply both sides of the equation by 6: x = 6 * 6 - Simplify the right side of the equation: x = 36

Therefore, the solution to the equation is x = 36. Please let me know if there are any other equations you would like me to solve!
