Question

Help! Will Fan And Medal!

Answer 1

What is the value of the expression \[\frac{ 4x-y }{ 2y+x }\] when x=3 and y=3

Answer 2

When both x and y are given (known), we substitute the values and evaluate numerically:
Given x=3, y=4
\(\Large\frac{ 4x-y }{ 2y+x }=\frac{ 4(3)-(4) }{ 2(4)+(3) }\)
Evaluate the expression and post your answer for a check if you wish.

Answer 3

oops, y=3.
\(\Large\frac{ 4x-y }{ 2y+x }=\frac{ 4(3)-(3) }{ 2(3)+(3) }\)

Answer 4

`??? makes no sense!`
please elaborate your statement.

Answer 5

\[=\frac{ 12-3 }{ 6+3 }=?\]

Answer 6

\[\frac{ 9 }{ 9 }?\]

Answer 7

you guys are useless!!!

Answer 8

9/9 is correct. Now you can further simplify one more time. Just like 2/4 is the same as 1/2, what do you think 9/9 is?

Answer 9

@kg1975 , if a two minute delay is enough to make us useless, then you might as well ask the calculator instead of us humans.

Answer 13

Would You Be Able To Help Me Some More?

Answer 14

Oh, ok. In that case, try asking someone else if you don't understand the person rather then replying in frustration, because otherwise others might misunderstand your frustration for anger, and not want to help you. It's just safer:) and yes, I can help you with another:)

Answer 17

@kg1975
That is why I asked you to elaborate the statement "makes no sense".
"Makes no sense" does not mean "I do not understand". It usually means that there is a mistake or something illogical.
To get help efficiently, you need to state the exact problem, and where the problem is.
Instead of saying helpers are useless, you just have to say I do not understand, and some helpers will backtrack to a point you can understand.
By the way, at Openstudy, we do not give out answers, at least not on a continual basis.
