Question

Rezolvati ecuatiile:

{[(123:3+362:2)-64·3+a]·182:2:7}-7·100:5=614

9236- [(3245-1236+63·4:2):5+a]+23124=31860

Answer 1

{[(123:3+362:2)-64·3+a]·182:2:7}-7·100:5=614

{[(41+181)-192+a]·91:7}-700:5=614

[(222-192+a)·13]-140=614

(30+a)·13=614+140

(30+a)·13=754

30+a=754:13

30+a=58

a=28


9236 - [(3245-1236+63·4:2):5+a]+23124=31860

32360 - [(3245-1236+252:2):5+a]=31860

32360 - [(3245-1236+126):5+a]=31860

32360 - [(2009+126):5+a]=31860

32360 - (2135:5+a)=31860

32360 - (427+a)=31860

32360 - 427 - a =31860

31933 - a =31860

a=31933 - 31860

a=73
