The substitution method is one way to solve systems of equations. You solve one equation for one variable, then substitute that expression into the other equation. It's like a game of math musical chairs - you keep substituting until you find the solution that works for both equations.
For example, let's say you have two equations: 2x + 3y = 7 and x - 2y = -3. You can solve the second equation for x, then substitute that expression into the first equation. It's like a math puzzle, and when you solve it, you'll find the values of x and y that make both equations true.
But here's a quirky fact: the substitution method can get really messy if you have complicated equations. That's where the elimination method comes in - it's like a math superhero that saves the day by eliminating one of the variables.
