How to solve - Solving Simultaneous Equation : Solving by Elimination Method?
- Group the equations into first (1) and second (2) equations.
- Two equations are simplified by adding or subtracting them.
- This eliminates one of the variables so that the other variable can be found.
- Find the other variable by substituting the first variable to either the two original equations
