Answer:
To find the first blank number, you can use reverse operations. Something + 7 must equal 3. So, the blank number is 7 subtracted from 3.
3-7=-4
The first blank number is -4. To find the second blank number, add 10 to the first blank number (-4).
-4+10=6
The second blank number is 6.
Hope this helps! :)
