Question

Fabio and Carlos play on a basketball team together. In the last game, Fabio had 777 points less than 222 times as many points as Carlos. Fabio scored 313131 points in the game.

Answer 1

222x-777=313131
Add 777 to both sides
222x=313908
divide 222 to both sides
x=1414
Carlos has 1414 points

Answer 2

Assuming it's 7, 2, and 31, you can set up (31+7)/2 is the amount that Carlos scored, which is 38/2 or 19.
