## FAQs on How to Solve Simple Equations? Video Lecture - Mathematics (Maths) Class 7

 1. How do you solve a simple equation?
Ans. To solve a simple equation, start by isolating the variable on one side of the equation. You can do this by using inverse operations. Perform the same operation on both sides of the equation to maintain its equality. Simplify the equation step by step until you obtain the value of the variable.
 2. What are inverse operations in solving equations?
Ans. Inverse operations are opposite mathematical operations that undo each other. The four basic operations (addition, subtraction, multiplication, and division) each have an inverse operation. For example, the inverse of addition is subtraction, and the inverse of multiplication is division. By using inverse operations, you can isolate the variable in an equation.
 3. How can I check if my solution to a simple equation is correct?
Ans. After solving a simple equation, you can check if your solution is correct by substituting the found value of the variable back into the original equation. If both sides of the equation are equal when you substitute the value, then your solution is correct. If the equation is not balanced, you need to recheck your calculations.
 4. Can a simple equation have more than one solution?
Ans. Yes, a simple equation can have more than one solution. This typically occurs when the equation contains variables with multiple values that satisfy the equation. For instance, the equation x + 2 = 5 has the solution x = 3. However, if the equation was x + 2 = 7, it would also have the solution x = 5. In such cases, the equation has infinitely many solutions.
 5. What should I do if I encounter fractions or decimals in a simple equation?
Ans. When dealing with fractions or decimals in a simple equation, it is often helpful to eliminate them by multiplying both sides of the equation by a common denominator. This will result in an equation with whole numbers. After solving the equation, you can simplify any fractions or decimals in the final solution if necessary.
