MAKE R the subject of the formulaq........ I =(mne) devide by (mR+nr)...........Its N2 math can u help?

It's not at all clear to me what your question is, what does this mean?

"MAKE R the subject of the formulaq........"

In this part, are we to take I,m.n.e,R and r as variables?

"I =(mne) devide by (mR+nr)"

What is N2 math?

"...........Its N2 math can u help?"

Is the formula I=(mne)/(mR+nr)?

yes it is I=(mne)/(mR+nr).

N2 math is the level i'm doing..i'm at the colledge. thanx for ur help.

You're welcome, but it would help to know what the question was seeking. We're given

"MAKE R the subject of the formulaq........ I =(mne) devide by (mR+nr)...........Its N2 math can u help"

So I=(mne)/(mR+nr).

Do we want to express R as a function of the other variables? I'm not really sure here. If so, then swap I and (mR+nr) to get

mR+nr =(mne)/I then

mR=(mne)/I - nr and finally

R=(1/m)[(mne)/I - nr]

Is that what was asked for here?

If so, I'll let you finish simplifying it.

Can you help me with an Algebra word Problem?
