Answer:
t + c = 623
t = c + 135
thomas has 379 songs downloaded, and carl has 244
Step-by-step explanation:
togheter they have 623 songs, aka the sum of thomas (t) and carl (c) is 623.
t + c = 623
thomas has 135 more than Carl. so Carl plus 135 is equal to thomas
t = c + 135
now you can solve it:
t + c = 623
(c+135) + c = 623
c + c = 488
2c = 488
c = 244
carl has 244 songs downloaded
t + 244 = 623
t = 379
thomas has 379 songs downloaded
