Question

(4/m)+(2/e)-(1/w)=0
solve for e.​

Answer 1

e = 2mw/ 4w - m

Explanation:

1. multiply both by e

4e/m + 2 - e/w = 0

2. Find LCM = mw. Multiply by it.

4ew + 2mw - me =0

3. subtract 2mw from both sides

4ew - ma = -2mw

4. divide both sides by 4w - m

e(4w - m) / 4w - m = -2mw / 4w - m

5. simplifly

e = 2mw/ 4w - m
