Substitution One equation is solved for one variable, and the result is substituted into the other equation to simplify the system.
Elimination By adding or subtracting equations, variables are eliminated, making it easier to solve for the remaining variable.
Graphical The equations are graphed, and the solution is the point where the graphs intersect.

For example, if you are given a system of two linear equations, you can use the substitution method by solving one of the equations for one variable and then substituting that expression into the other equation. Alternatively, with the elimination method, you can multiply one or both equations by factors that allow you to cancel out one of the variables when added or subtracted.

By choosing the most efficient method based on the problem, you can solve systems of equations more quickly and accurately, saving time and reducing complexity.
