Answer:
3
Step-by-step explanation:
10 - 4 = 9 - __.
First, look at the first half of the problem (the left of the equal sign). Solve.
10-4 = 6.
So now you know that 9 minus something has to equal 6.
10-4 = 6.
6 = 9 - ___.
Nine subtracted by what number equals 6? You can count on your fingers, draw a picture, or subtract 6 from 9.
9-6=3.
Answer is 3.
(10-4 = 9-3)
