Question

Whats the answer to this equation 10-4=9-[]​

Answer 1

It would be 3 because 10-4=6 and 9-3=6 you really just need to find the number that will lead to the same answer as the other

Answer 2

We can write this expression as 10 - 4 = 9 - x

10 - 4 = 9 - x

6 = 9 - x

6 - 9 = 9 - x - 9

-3 = -x

-3/-1 = -x/-1

3 = x
