I consider this inquiry as pretty easy as you only need to figure out the the first line then the rest is easy.First I used and educated guess for the triangle and the square but then worked my way from there adding 1 to the first number and taking one from the second until I got 8 and 6 .Then my strategy from there was to add the numbers I knew together (if they were in the row/column)then calculating in my head how many more units I needed to get to the row/column answer, if there was two of the same shape I halved the answer I got.
