Answer:
1300
Step-by-step explanation:
Let the amount put in the station's tank = x
4(400 + x) = 8100 - x Remove the brackets
1600 + 4x = 8100 - x Subtract 1600 from both sides
1600 - 1600 + 4x = 8100 - 1600 - x Do the subtraction
4x = 6500 - x Add x to both sides
4x + x = 6500 - x + x
5x = 6500 Divide by 5
5x/5 = 6500/5
x = 1300
1300 gallons were added to the station's tank.

Answer:
Step-by-step explanation:
(-x + 3) - (4x - 10)
= - x + 3 - 4x + 10 (because when you see the minus sign you have to change all the sign inside the bracket)
= -5x + 13 (this step is just subtract -x and -4x and 10 + 3)
