## FAQs on Linear Equations CAT Previous Year Questions with Answer PDF

 1. What are linear equations?
Ans. Linear equations are mathematical equations that can be written in the form of ax + b = 0, where x is the variable, a and b are constants. The solutions to a linear equation form a straight line when plotted on a graph.
 2. How are linear equations solved?
Ans. Linear equations can be solved using various methods such as substitution, elimination, or graphing. The aim is to isolate the variable on one side of the equation and find its value.
 3. Can linear equations have more than one solution?
Ans. Yes, linear equations can have one solution, no solution, or infinitely many solutions. The number of solutions depends on the relationship between the coefficients and constants in the equation.
 4. What is the importance of linear equations in real life?
Ans. Linear equations are widely used in various fields such as physics, engineering, economics, and finance. They are used to model and solve real-life problems involving relationships between variables, such as finding the cost of goods, calculating distances, or predicting future trends.
 5. Are there any shortcuts or tricks to solve linear equations quickly?
Ans. While there are no specific shortcuts, there are some techniques that can make solving linear equations easier. These include simplifying the equation, using the distributive property, or dividing both sides of the equation by a common factor to eliminate fractions. Practice and familiarity with different methods will also improve solving speed.
