## FAQs on RD Sharma Class 7 Maths Solutions Chapter 8 - Linear Equations in One Variable

**1. How many solutions can a linear equation in one variable have?**

Every linear equation in one variable has a one and unique solution. If the equation has two or more variables then it known as a linear equation in two variables or linear equations in three variables and so on. The number of solutions varies according to the count of variables an equation contains.

**2. What is the application of linear equations?**

There are various applications of linear equations in real life such as solving word problems involving relationships between numbers. In geometry, problems involving perimeter, solving percentage and money problems including simple interest can also be done using linear equations.

**3. How many solutions can a linear equation in one variable have?**

The Equation in which the highest power of the variable is always 1 is known as a linear equation. It is also called a first-degree equation. Every linear equation in one variable has one and unique solution. If the equation has two or more variables then it is known as a linear equation in two variables or linear equations in three variables and so on. The number of solutions varies according to the count of variables an equation consists of.

**6. What are linear equations?**

The equation in which the highest power of the variable is always 1 is called a linear equation. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, and A, B and C are constants. It is also known as the one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, and A and B are constants.

**7. What are some facts related to linear equations?**

If a number is added, subtracted, multiplied, or divided into both sides of the equation then the solution of a linear equation remains unaffected.

The value of the variable which makes a linear equation true is known as the solution or root of the linear equation.

The graph of a linear equation with one or two variables forms a straight line.
