Answer:
Joseph caught 7 tadpoles 
Step-by-step explanation:
Let the number of tadpoles caught by Joseph be x 
The number of tadpoles Wendy caught will be ;
9(x + 3) 
After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;
Hence, mathematically;
9(x + 3)/2 - 6x = 3 
Multiply through be 2 
9(x + 3) - 12x = 6
9x + 27 -12x = 6
9x -12x = 6-27
3x = 21
x = 21/3
x = 7
