Answer 3

You cannot solve for b. There are more than 1 variable.

As for what @TAKEBACKMATH did, he changed the subject of the equation.

Answer 4

oh okay then can you help me create my own literal equation and solve for a variable and explain how you solved for that particular variable @tyteen4a03

Answer 5

no sorry, I did exactly what was asked, solved for b

Answer 6

@TAKEBACKMATH is it possible to have more than 2 variables?

Answer 7

Takebackmath is correct

Answer 8

Answer 9

@TAKEBACKMATH can you explain how you did that for me

Answer 10

@subbyh What is the assignment?

To change subject for this equation A=(a+b)/2, here's how it's done:
2A=a+b
2A-a=b

Answer 11

Hey math legend relax, I understand I need to show steps. I am a math teacher I understand

Answer 12

now im confused lol the one with the explanation by @tyteen4a03 is correct??

Answer 13

The goal here guys, is to guide the asker towards the answer. Please do not give the final answer unless it is unavoidable or the asker already knows it.

Answer 14

@subbyh What is the assignment? I think the above conversation was driving you away from the actual question.

Answer 15

for instance it would be better to say:
multiply by 2
subtract a
then see what the asker says, no final answer needed

Answer 16

it is an FLVS assignment and what was asked was to Create your own unique literal equation and solve for one of the variables. Show your work. Then, using complete sentences, explain how you solved for the variable you chose.

so i chose that equation i suppose i chose a rather difficult one

Answer 17

not really...
1) multiply both sides by 2
2) subtract a from both sides
try it, and please show your work

Answer 18

i get stuck on the subtracting a part, does it matter if it is A or a

Answer 19

Yes. A differs from a, and capital letters are usually used to denote constants.

Answer 20

2A=a+b

2A-a=b

is that correct

Answer 21

yes :)

Answer 22

thank you :)
