Solving+3x3+Systems!!!

Click [|here] for a pretty cool link! Yeah! Math!

So. Solving 3X3 Systems of equations is madd easy. Here are the steps: 1. Solve to eliminate one common variable in two equations. 2. Solve for one variable and substitute the answer into THE OTHER problem.3. Solve for the other variable.4. Plug the variables into an original equation.5. Write the answer in the proper way!

Here's an example!

You can do this step in many different ways! All you need to do is create two equations where one of the three variables is missing. Yes that sounded very tricky when wording it, but it's not bad I promise you!



AND

NEXT take the one equation and solve for a common variable! THEN use substitution and fill in the common variable in the other equation to find the other variable.

FINALLY plug the solutions you found in an equation with all variables. Solve for the last variable left :)

YOU'RE DONE! WOO-HOO! Just write the answer in the proper format and you're all set!
