Key Concepts

Linear Equations

A linear equation in one variable is an equation that can be written in the form ax + b = 0, where 'a' and 'b' are constants and 'a' is not zero. This type of equation represents a straight line when graphed, and solving it involves finding the value of the variable that makes the equation true.

Combining Like Terms

Combining like terms is the process of simplifying an equation by adding or subtracting terms that have the same variable components. This technique reduces the equation to a simpler form, making it easier to solve by reducing the number of terms involved.

Isolating the Variable

Isolating the variable refers to the technique of rearranging an equation so that the unknown variable stands alone on one side of the equation. This process generally involves inverse operations, such as adding, subtracting, multiplying, or dividing both sides of the equation by the same value to maintain equality.
