Best ResponseYou've already chosen the best response.0I assumed from the answer choices that was the problem, but you still have not answered, if a,z, and x were just numbers instead of variables, could you find y?

Best ResponseYou've already chosen the best response.0ok, so can you tell me the order of operations?

Best ResponseYou've already chosen the best response.0i really know nothing about this thats why i need help

Best ResponseYou've already chosen the best response.0Well, then at least google the order of operations. You should have learned that in 5th or 6th grade.

Best ResponseYou've already chosen the best response.0I would like to know the whole order, for example, people like to use PEMDAS to remember, can you tell me what each letter stands for?

Best ResponseYou've already chosen the best response.0alright, so it is important to remember the order of operations because when you solve for a variable, you just reverse it. So we will do SadMep

Best ResponseYou've already chosen the best response.0So, first we write what the question actually means \[a=\frac{(x+y+z)}{3}\] Now, we reverse the order of operations and ask ourselves, is there any subtraction?

Best ResponseYou've already chosen the best response.0but it is inside parentheses right? So we have to wait

Best ResponseYou've already chosen the best response.0so now, keep going, what comes after addition when we reverse the order of ops?

Best ResponseYou've already chosen the best response.0right, so what is the opposite of division?

Best ResponseYou've already chosen the best response.0good, so if we are dividing by 3, to undo it, we need to multiply both sides by 3, can you tell me what you get?

FibonacciChick666

Best ResponseYou've already chosen the best response.0nice, so now, restart your reversal of the order of ops

Best ResponseYou've already chosen the best response.0ok, so what are we trying to get by itself?

Best ResponseYou've already chosen the best response.0and how do we undo addition?

Best ResponseYou've already chosen the best response.0do we subtracts y and z

FibonacciChick666

Best ResponseYou've already chosen the best response.0well, we want y so we will leave it. If we subtracted y and z from bothe sides, we'd find x not y. So what do we need to subtraact from both sides?

Best ResponseYou've already chosen the best response.0yea, and what do you get?

FibonacciChick666

Best ResponseYou've already chosen the best response.0no, remember you have to do it to both sides

FibonacciChick666

Best ResponseYou've already chosen the best response.0nah, just write the whole thing out. you are here: \[3a=x+y+z\]
