There are three ways of solving systems of linear equations: graphing, substitution, and elimination. Post a problem, and show your step-by-step solution using one of the three methods. Now go and check out a classmate’s problem and solution. Are they correct? If not, are you able to point out their error so they can fix it?
Don’t forget to do a check. Put your solution into your original problem. Does it work
