76502 - x = 10512 : 32
76502 - x = 328,5
x = 76502 - 328,5
x = 76173,5
x + 532 = 48 x 23
x + 532 = 1104
x = 1104 - 532
x = 572
x - 264 = 1456 : 56
x - 264 = 26
x = 26 + 264
x = 290
nhớ tk mik đó
Bài a:
76502 - y = 10528 : 32
76502 - y = 329
y = 76502 - 329
y = 76173
Bài b:
y + 532 = 48 x 32
y + 532 = 1536
y = 1536 - 532
y = 1004
Bài c:
(y - 264) x 52 = 1456
y - 264 = 1456 : 52
y - 264 = 28
y = 28 + 264
y = 292
Lưu ý: Tớ không chắc là đúng hết nha! Xin hãy cẩn thận. Nếu đúng, chọn đúng và kết bạn với mình nha!
76502-x=328,5
x=76502-328,5
x=76173,5 nhé bn k cho mk nha nha nha
