Đáp án:
Giải thích các bước giải:
x – 2/5 = 7/10 x – 25/16 = 5/64
x = 7/10 + 2/5 x = 5/64 + 25/16
x = 11/10 x = 105/64
x – 5/4 = 7/24 x – 9/8 = 5/16
x = 7/24 + 5/4 x = 5/16 + 9/8
x = 37/24 x = 23/16
x – 3/4 = 4/5 + 1/3 x – 3/5 = 5/9 + 5/3
x – 3/4 = 17/15 x – 3/5 = 20/9
x = 17/15 + 3/4 x = 20/9 + 5/3
x = 113/60 x =35/9
