Answer:

Step-by-step explanation:

okay, so here are a few methods you can use.

___

1) +

x + 7 = 10 so because this is addition we use the reverse, subtraction. So

x - 7 = 10 - 7 and that equals to 3.

2) -

x - 2 = 10 so because this is subtraction we do the reverse, addition.

x + 2 = 10 + 2 and that equals to 12.

3) x

x times 3 = 21 because this is multiplying we divide.

x/3 = 21/3 and that would be 7.

4) /

x/2 = 10 same as above, reverse is multiplying.

x times 2 = 10 times 2 and thats 20.
