Our goal is to isolate n. In order to do this, we must first get rid of the 15 on the left side of the equation.
To achieve this result, we must do the inverse of the operation on both sides of the equation. In other words, subtract 15 from both sides.
8n + 15 - 15 = 25 - 15
8n = 10
Now we must get rid of the 8, by again doing the inverse of the operation. Since 8 is multiplying n, we must divide it into both sides.
8n / 8 = 10 / 8
n = 1.25
Hopefully, this helps!
Type o ( ii) = 6 . 25
Type A ( l^A l ^A or l ^A i ) = 18 . 75
Type B ( l ^b l^b or l ^ bi ) = 18.75
Type AB ( l ^ A l^ B) = 56.25

1: Triple the quantity of a number “n” plus 4 equals 27. what would the expression look like?
[ Triple the quantity of a number “n” ] 3n
[ plus 4 ] + 4
[ equals 27 ] = 27
[ all together ] <u>3n + 4 = 27</u>
<u />
<u>Solving:</u>
[ given ] 3n + 4 = 27
[ subtract 4 from both sides ] 3n = 23
[ divide both sides by 3 ] n = 7
2:Seventeen equals seven less than three times a number “n” what would the expression look like?
[ Seventeen equals ] 17 =
[ seven less than ] - 7
[ three times a number “n” ] 3n
[ all together ] <u>17 = 3n - 7</u>
<u />
<u>Solving:</u>
[ given ] 17 = 3n - 7
[ add 7 to both sides ] 24 = 3n
[ divide both sides by 3 ] 8 = n
Have a nice day!
