Answer:
Step-by-step explanation:
Let x represent the number of 3-lb bags purchased. Then the total purchase was ...
   $2(8 -x) +$5.50(x) = $37
   16 +3.50x = 37 . . . . . . . . . divide by $, collect terms
   3.50x = 21 . . . . . . . . . . . . . subtract 16
   21/3.50 = x = 6 . . . . . . . . divide by the coefficient of x
You bought 6 3-lb bags of peanuts and 2 1-lb bags.
 
        
             
        
        
        
Answer:
1. No
2. No
3. No
4. Yes
Step-by-step explanation:
Plug each option into u then solve the equation and see if the answer matches -15.
Ex. -15 = 1 -4 (2)
      -15 = 1 -8
      -15 = -7
      -15 does not equal -7 therefore it is false. Use Pemdas to solve.

Answer:
1. Add 6 to both sides, cause that is the inverse of subtraction, so you get 5x = 50 as 6 cancels 6 out.
2. Divide 5 from both sides and get x = 10
