Question

So 0.3(n - 5) = 0.4 - 0.2n N=? What is N?

Answer 1

Answer:

n = 3.8

Step-by-step explanation:

0.3(n - 5) = 0.4 - 0.2n

Distribute

.3n - 1.5 = .4 - .2n

Add .2n to each side

.3n +.2n -1.5 = .4 -.2 +.2n

.5n -1.5 = .4

Add 1.5 to each side

.5n -1.5 +1.5 = .4+1.5

.5n = 1.9

Divide each side by .5

.5n/.5 = 1.9/.5

n =3.8
