Best ResponseYou've already chosen the best response.0u set it up like t7 +7

Best ResponseYou've already chosen the best response.0okay very good. so if you add 7 to the left hand side of the equation, you must add it to the right hand side also to make the equation equal. so t  7+7 = 18+7

Best ResponseYou've already chosen the best response.0in the earlier problem, you found out t = 25.

Best ResponseYou've already chosen the best response.0so this set up will be like 4+4 = b4+4

Best ResponseYou've already chosen the best response.0your equation was t  7 = 18 so what is t?. if you put t = 25, you get 25 minus 7 is 18. which is exactly right. similarly in your new problem, it is: some number b  4 gives 4

Best ResponseYou've already chosen the best response.0just put it in words. b4 = 4 means " the number BEE minus the number 4, gives me a number 4". so what is BEE?

Best ResponseYou've already chosen the best response.0exactly. and you know b = 8 because 8 minus 4 is equal to 4.
