Question

C•8-9344=24520. 5689+7•а=23665

Answer 1

С*8-9344=24520
с*8=24520+9344
с*8=33864
с=33864/8
с=4233

5689+7*а=23665
7*а=23665-5689
7*а=17976
а=17976/7
а=2568

Answer 2

С*8 - 9 344 = 24 520
с*8 = 24 520 + 9 344
с*8 = 33 864
с = 33 864 : 8
с = 4 233


5 689 + 7*а = 23 665
7*а = 23 665 - 5 689
7*а = 17 976
а = 17 976 : 7
а = 2 568
