To check your answers after solving systems of linear equations, you can use these simple methods:
Substitution Method: Take the value of one variable and plug it into the other equation. Make sure both sides equal each other.
Elimination Method: After you find the solution, put both variable values back into the original equations. Check if they match.
Graphical Method: Draw both equations on a graph. See if they cross at the solution point.
Remember, checking your work helps make sure your answers are right. It also builds your confidence in solving problems and understanding concepts better!
