Sagot :
Answer:
You need to fix some mistakes in the 2nd, 3rd column and the 1st column..
In the second column, you didn't make 17 negative.
In the third column, you didn't multiply 7x6 right. It doesn't equal 40, it is 42. You also made 2 and 5, a negative when it's supposed to be a positive
In the first column, for -5+8, you made it a negative instead of a positive. It should be a positive 3.
