To get really good at the elimination method in algebra, here are some easy steps to follow:
Line Up the Equations: Make sure to write the equations neatly. Put the variables in the same place in both equations.
Multiply If You Have To: If the numbers in front of the variables (the coefficients) don’t match, multiply one or both equations. This will help create matching numbers.
Add or Subtract: Now, combine the equations by adding or subtracting them. This will get rid of one variable, and you can then solve for the other one.
Double-Check Your Answer: Always plug your answer back into the equations to make sure it’s right!
