Reorder the terms:
-19 + 4n = 13
Solving
-19 + 4n = 13
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '19' to each side of the equation.
-19 + 19 + 4n = 13 + 19
Combine like terms: -19 + 19 = 0
0 + 4n = 13 + 19
4n = 13 + 19
Combine like terms: 13 + 19 = 32
4n = 32
Divide each side by '4'.

Answer:
station A
Step-by-step explanation:
Given data
We are told that she has $85 and she wants to fill only her tank
station A
charges $2.67 per gallon
12 gallons will cost

=$32.04
station B
charges $2.60 per gallon
12 gallons will cost
=12*2.60
=$31.2
station C
charges $2.62 per gallon
12 gallons will cost
=12*2.62
=$31.44
The cheapest is station A
100.
formula: base•height/2
8•10/2= 40
12•10/2= 60
60+40= 100
