Key Concepts

Checking Solutions

Checking solutions involves substituting the obtained value back into the original equation to verify that it satisfies the equation. This process ensures that no errors were made during the solving process and confirms the correctness of the solution.

Inverse Operations

Inverse operations are mathematical operations that reverse the effect of another operation. For example, dividing by a number is the inverse of multiplying by that number. In solving equations, these operations are used to isolate the variable.

Linear Equations

Linear equations are equations that involve variables raised only to the first power. They can be solved by isolating the variable on one side of the equation using algebraic operations such as addition, subtraction, multiplication, and division.
