Let x be the average monthly rainfall.
So, you would get the equation:
2 1/3+7 2/3=x

What do you have to do to find x?

anonymous · Answer

x - 7 2/3 = 2 1/3
That's how they want you to set it up

anonymous · Answer

To solve that ... what do you do to both sides?

anonymous · Answer

This is an absolutely ridiculous question though, because no reasonable person would use algebra to solve this. Just add 7 2/3 and 2 1/3 to get the answer.

anonymous · Answer

x - 7 2/3 = 2 1/3
To get rid of the 7 2/3....add 7 2/3 to both sides.

Ok
