9/14 - x/7 : 5/3 = 3/14
9/14 - x x 1/7 x 3/5 = 3/14
x x 3/35 = 9/14 - 3/14
x x 3/35 = 3/7
x = 3/7 : 3/35
x = 5
vậy x =5
9/14 - x/7 : 5/3 = 3/14
9/14 - x x 1/7 x 3/5 = 3/14
x x 3/35 = 9/14 - 3/14
x x 3/35 = 3/7
x = 3/7 : 3/35
x = 5
vậy x =5
tìm x biết 9/14 -x/7 /5/3 =3/14
lưu ý :các số như 9/14 là phân số
Tìm x :
a, x - 3/2 = 4/3 b, 2/5 * x = 1/3
c, x - 4/9 = 3/7 : 9/14 d, 3/5 * x - 1/2 = 1/5
tim x 9/14-x/7:5/3=3/14
9/14 - x/7 : 5/3 = 3/14 tim x
1.tìm x
X x 6/7=5/14 X : 2/3=4/9
X-1/4=3/2 X+4/5=8/9
9/5 : 7/4 + 3/4x8/7 7 x 3/14 - 1/14
9/14-x/7:5/3=3/14
x=?
