It takes 4 liters to make a gallon, there are 15 liters so therefore that would be 3 gallons and 2 liters.
-(7x + 4)- 2x + 2 = 52
Distribute the negative sign:
-7x -4 - 2x + 2 = 52
Combine like terms:
-9x - 2 = 52
Add 2 to both sides:
-9x = 54
Divide by -9:
x = -6
Answer: x = -6
$312.50 = p x 0.25 x 25
