What are Linear Equations in One Variable?

A linear equation in one variable is an equation that can be written in the form ax + b = c, where x is the variable and a, b, c are numbers. The highest power of the variable is 1.

Examples:
1. 2x + 3 = 7
2. 5y - 10 = 0
3. z/4 + 6 = 10

Why is this important?
Linear equations help us solve real-life problems like finding ages, distances, prices, and more. Mastering this chapter will make future topics like algebra, word problems, and even science much easier!

Did You Know? The concept of linear equations dates back to ancient Babylonian and Egyptian mathematics—over 4000 years ago! Solving equations helped people trade goods, measure land, and even build pyramids.
