Given:
Joey had 26 game cards.
His friend Richard gave him some more, and now Joey has 100 cards.
To find:
How many cards did Richard give to Joey?
Solution:
Let x be the number of cards that Richard give to Joey.
Joey had 26 game cards.
Now, the total cards joey has [tex]=26+x[/tex]
Joey has total 100 cards.
[tex]26+x=100[/tex]
[tex]x=100-26[/tex]
[tex]x=74[/tex]
Therefore, Richard gave him 74 cards.
