1. In a system of equations, what does it mean to solve using elimination?
Solving using elimination means to manipulate the equations in the system in such a way that when added together or subtracted from each other, one of the variables is eliminated, making it easier to solve for the other variable.
2. When using elimination, what should you do if the coefficients of one of the variables in the two equations have the same value?
If the coefficients of one of the variables in the two equations have the same value, you should multiply one or both of the equations by a constant so that when added or subtracted, the variable is eliminated.
3. What is one advantage of using elimination to solve a system of equations?
One advantage of using elimination to solve a system of equations is that it allows you to quickly eliminate one of the variables, making it easier to solve for the other variable in a shorter amount of time.
4. How can you check your solution when using elimination to solve a system of equations?
You can check your solution by substituting the values of the variables back into the original equations and verifying that they satisfy both equations. If the values satisfy both equations, then the solution is correct.
