Answer:
-2/3
Step-by-step explanation:
multiply each side by u +1 to get it out of the denominator
-3(u + 1) = -1

-3u - 3 = -1
add the 3 to move it over
-3u = 2
now divide by -3
u = -2/3
Answer:
I believe it would be 86 cups left of milk.
Step-by-step explanation:
8 gallons= 128 cups of milk
3 quarts= 12 cups
Plus the 1 cup of milk he had equals 141 of milk in total
Now the customer wants 2 gallons (32 cups of milk), 5 quarts ( 20 cups), and 3 cups which is 55 cups of milk.
Now we minus what the customer bought from what the shop keeper had so:
55-141=86
