∴ In 70 hour, The quantity of water filled in bucket = \dfrac{4}{24} × 70 gallon

I.e x = \frac{4\times 70}{24} gallons

Or, x = 11.67 gallons

Solve the equation: -2x+13=-7x+28
natali 33 [55]

Answer:

x = 5

Step-by-step explanation:

-2x + 13 = -7x + 28

Subtract 13 on both sides

-2x + 13 - 13 = -7x + 28 - 13

-2x = -7x + 15

Add 7x on both sides

-2x + 7x = -7x + 7x + 15

5x = 15

Divide by 5 on both sides to isolate the variable

5x/5 = 15/5

x = 5

Hope this helped!
