Question

Explain linear equations in one variable.

Answer 1

A linear equation in one variable is an equation which has a maximum of one variable of order 1.

It is of the form ax + b = 0, where x is the variable.

• ‘a’ and ‘b’ are real numbers.
• Both ‘a’ and ‘b’ are not equal to zero.

This equation has only one solution. A few examples are:

$$\begin{gathered} 3x=1 \\ 22x–1=0 \\ 4x+9=-11 \end{gathered}$$
