Sylvia buys a case of water that contains 24 bottles and sells x number of bottles to her co- workers. Sam buys a case of water that contains 36 bottles and sells three times as man bottles as Sylvia sold to his co-workers. How many bottles of water did Sylvia sell if they ended up with the same number of bottles of water left over?

6 bottles

Step-by-step explanation:

Given the following :

SYLVIA:

Case of water = 24 bottles

Number of bottles sold = x

SAM:

case of water = 36 bottles

Number of bottles sold = 3x

Number of bottles left after sales are the same ;

Number of bottles left :

24 - x = 36 - 3x

Then solve for x

-x + 3x = 36 - 24

2x = 12

x = 12/2

x = 6

Hence, Sylvia sold 6 bottles of water.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
