vova2212 [387]

Answer:

n=-0.04761

Step-by-step explanation:

given $2\div 9n$ -5=2+ $5\div 9n$

$2\div 9n$ - $5\div 9n$ =2+5

$\frac{2-5}{9n}$ =7

-3= $7\times 9n$

63n=-3

n= $\frac{-3}{63}$ =-0.04761

Solve for n.<br> -6n = -5 - 5n<br> n=

goblinko [34]

1. Simplify both sides

−6n=−5−5n

−6n=−5+−5n

−6n=−5n−5

2. Add 5n to both sides

−6n+5n=−5n−5+5n

−n=−5

3. Divide both sides by -1.

−n /−1 = −5 /−1

n=5

So the variable n, is equal to 5
