8 + ____ = 20
To figure out what would go in the blank, take the opposite of adding 8, and subtract 8 from 20. 20 - 8 = 12. Now check your work! 8 + 12 = 20 20 = 20 (Check!)

10x5=50 For this problem you can multiply the 1x5 then add the 0 at the end since you are multiplying by 10.
Start out by trying to isolate the "x" variable. To undo adding 4, you need to do the opposite which is to subtract 4 on both sides. This leaves you with 2x=8 To undo multiplying by two, do the opposite which is dividing by 2 This leaves you with x=4. To check your work, you can plug back in your answer. 2(4)+4=12 8+4=12 12=12 (Check!)
