can someon help please.
why is it important that you follow the steps rather than solve the problem from left to right?I have no clue. this is my first time taking algebra
The language of Algebra is precise, and built into it is an expectation that the user will follow the order of operations rules. Going from left to right is not in those rule, and can lead to erroneous results.
You have to follow the Order of Operations. Try this phrase out. "Please Excuse My Dear Aunt Sally" PEMDAS
P=parantheses E= Exponents M=Multiplication D=Division A=Addition S=Subtraction
It sounds stupid but it works.

Systems of equations can be solved by graphing or by using substitution or elimination. What are the pros and cons of each method? Which method do you like best? Why? What circumstances would cause you to use a different method? Consider responding to your classmates by indicating pros and cons they may not have considered or persuading them to see the value of the method you like best (if you chose different methods). Describe situations in which you might use their methods of solving.
