Eric had 143 baseball cards. his uncle gave him a number more. then eric gave his friend 26 cards. he has 184 cards now. how many cards did eric's uncle give him?

Eric's uncle gave him 67 cards.

Step-by-step explanation:

We know that:

the number of baseball cards Eric had earlier = 143,

the number of cards Eric's uncle gave him = x,

the number of cards Eric gave to his friends = 26, and

the number of cards Eric is left with = 184

So before giving 26 cards to his friend, Eric had = 184 + 26 = 210

and initially he had 143 cards.

Therefore, his uncle gave him = 210 - 143 = 67 cards.
