a) x + 1/9 – 1/8 = 1/6 x = 1/6 – 1/9 + 1/8 x = 13/72 Vậy x = 13/72 b) 5/16 – x + 5/11 = -5/6 -x = -5/6 – 5/16 – 5/11 -x = -845/528 x = 845/528 Vậy x = 845/528 c) 1/5 + x – 7/3 = 1/2 x = 1/2 – 1/5 + 7/3 x = 79/30 Vậy x = 79/30 d) x/5 – 2/3 + 3/4 = 17/60 x/5 = 17/60 + 2/3 – 3/4 x/5 = 1/5 x = 1 Vậy x = 1 e) -1/3 – x – 4/5 = 4/15 -x = 4/15 + 1/3 + 4/5 -x = 7/5 x = -7/5 Vậy x = -7/5 Bình luận
Đáp án:
a. x+1/9 – 1/8 =1/6
x + 1/9 = 1/6 + 1/8
x + 1/9 = 4/24 + 3/24 = 7/24
x = 7/24 – 1/9
x = 21/72 – 8/72
x = 13/72
b) 5/16-x + 5/11 =-5/6
5/16 – x = -5/6 – 5/11
5/16-x = -55/66 – 30/66 = -85/66
x = 5/16 + 85/66
x = 0.00005570409
c.1/5+x-7/3=1/2
1/5 + x = 1/2 + 7/3
1/5 + x = 17/6
x =17/6 – 1/5 = 0.96
d. x/5-2/3+3/4=17/60
x/ 5 – 2/3 =17/60 – 3/4
x/5 – 2/3 = -0.46
x/5 = -0,46 + 2/3
x/5 = 0.2
x = 1
e. -1/3-x-4/5=4/15
-1/3 – x = 4/15 + 4/5
-1/3-x = 16/15
x = -1/3 – 16/15
x = -1,4
a) x + 1/9 – 1/8 = 1/6
x = 1/6 – 1/9 + 1/8
x = 13/72
Vậy x = 13/72
b) 5/16 – x + 5/11 = -5/6
-x = -5/6 – 5/16 – 5/11
-x = -845/528
x = 845/528
Vậy x = 845/528
c) 1/5 + x – 7/3 = 1/2
x = 1/2 – 1/5 + 7/3
x = 79/30
Vậy x = 79/30
d) x/5 – 2/3 + 3/4 = 17/60
x/5 = 17/60 + 2/3 – 3/4
x/5 = 1/5
x = 1
Vậy x = 1
e) -1/3 – x – 4/5 = 4/15
-x = 4/15 + 1/3 + 4/5
-x = 7/5
x = -7/5
Vậy x = -7/5
