Yx5+240=3045
Tính 30 45 - 2 5
30 45 - 2 5 = 2 3 - 2 5 = 10 15 - 6 15 = 4 15
Đặt tính rồi tính

1468+7032:6-3045:5
Ai trả lời nhanh sẽ tk cho nha!
1468+7032:6-3045:5
= 1468+1172-609
= 2640-609
= 2031
1468 + 7032 : 6 - 3045 : 5
= 1468 + 1172 - 609
= 2640 - 609
= 2031
yx5-2425= 36850
y x 5 = 36850 + 2425
y x 5 = 39275
y = 39275 : 5
y = 7855
`y xx 5 = 39275`
`=> y = 7855`.
