Answer:
15 lb
Step-by-step explanation:
let the current weight of the puppy be X, the initial weight of the puppy is 4lb or , (6 lb less 2/3 X) .
#We equate the current weight to the initial weight to determine X:
Hence, the current weight of the puppy is 15 lb

<h2>Explanation:</h2>The complete question is attached below. In order to solve this problem, we'll use a graphing tool. First of all, we'll say that the LHS is a linear function and the RHS is another linear function, so for each case, we'll have:
For each graph, will be drawn in red while
will be drawn in blue.
Case 1:
So by equating both equations:
By using graphing tool we get a point of intersection at which the x-value is the solution to our equation. So:
