Overview
ALGEBRAIC EQUATIONS
Algebraic equations must be solved in a formal way so that everyone can understand what you are doing and to make it clear. To solve an equation formally you must follow the steps below.
Algebraic equations must be solved in a formal way so that everyone can understand what you are doing and to make it clear. To solve an equation formally you must follow the steps below.
- Write the given equation
- If necessary, expand any brackets and collect like terms
- Isolate the variable using inverse operations and to maintain balance. Repeat if necessary.
- Check your solution to see it it satisfies the equation. LHS=RHS
