1 gallon is 4 quarts or 8 pints. 9 gallons - 3 gallons= 6 gallons
Then convert it to quarts so, 6×4=24 quarts.
Then subtract that by 10 quarts so, 24-10=14 quarts.
Because you requested the number in pints, you have to convert it again and because there are 2 pints in a quart you multiply it by 2 so, 14×2=28 pints left over.
There is no algebraic way of isolating X unfortunately.
For these equations, you have to solve with numerical approximation.
I suggest Newtons method if you know calculus.
To find an average you take the numbers to be averaged and add them together then You take the number and divide it by the number of numbers, in this case 4, and that gives you the average.
on this problem you want to do the opposite. you know the average she wants, an 87, so you multiply it by 4. 87*4=348. then you add the three numbers you have (88,81 and 87) and you get 256.
then you subtract 256 from 348 and you get 92. 92 is your answer to check just add 87+81+88+92=348
348/4=87
87 was the average she wanted.
Hope this helped! good luck :)
