Using a Multiplier to Solve the System of Equations Using Elimination

The video tutorial explains the elimination method for solving systems of equations, contrasting it with the substitution method. It emphasizes the importance of matching coefficients before adding or subtracting equations. The tutorial guides through identifying the least common multiple of coefficients, applying the elimination method, and solving for variables. It concludes with a demonstration of finding the solution and highlights the flexibility in choosing which equation to substitute the solved variable into.

What should you do after multiplying the equations to have the same coefficients?

When solving for Y, does it matter which equation you plug the value into? Explain your answer.
