Question

So my teacher gave us the answer to this, but he said we have to do the work and I have tried it numerous times and still can’t get the work. So, I need help please. Problem: 1.3n-0.03=-9

Answer 1

Hey there!

First, reorder the terms:
-.03+1.3n= -9
Then move the terms that contain an "n" to the left, and all with no variables to the right
Add -.03 to each side
-.03+-.03+1.3n= -9+.03
Combine the like terms
0.00 + 1.3n = -9 + 0.03 1.3n = -9 + 0.03 -9 + 0.03 = -8.97 1.3n = -8.97
Then divide each side by 1.3 and you will get
n= -6.9

Hope this helps! :)

Answer 2

1.3n-0.03 = -9

add 0.03 to each side

1.3n = -8.97

divide both sides by 1.3

n = -8.97 / 1.3

n= -6.9
