What is the answer ?how can I find it?
ExtremeBDS [4]
First you would add the dog+puppy food. Then you would subtract the total amount of lbs of food from dog+puppy food. You would then be left with only the cat food.

50-19.75+18.875

50-38.625

= 11.375

The final answer: You would have 11.375 lbs of cat food.

108 - 271 + 215-_____= -103
kupik [55]
108-271+215-_____=-103
Im going to combine the first thee numbers and replace the blank with a variable, lets use x. 
52 - x=-103
now I am going to subtract 52 on both sides to get the variable alone
-x=-155
Im going to multiply both sides to eliminate the negitive in the variable
x=155
If you want to check just plug 155 into the blank
108-271+215-155=-103
-163+215-155=-103
52-155=-103
-103=-103

so after checking work the blank is equal to 155.
