a) x - 5/7 - 13/14 = 1
⇒ x - ( 5/7 + 13/14 ) = 1
x - 23/14 = 1
x = 1 + 23/14
x = 37/14
b)
⇒ 3/5 + x+ 6/5 = 11/3
x + 9/5 = 11/3
x = 11/3 - 9/5
x = 28/15
1) Tìm x:
a) x - 5/7 -13/14 = 1
b) 3/4 + x 1 1/5 = 11/3
1 1/5 là hỗn số nhé
Tìm x
a) 1/2 : 3 + x = 14/5
b) 8/5 : x : 7/4 = 11/6
c) 24/10 + x : 3/4 = 11/3
Tìm \(x\):
a)\(x-\dfrac{5}{7}-\dfrac{13}{14}=1\) b)\(\dfrac{3}{5}+x+1\dfrac{1}{5}=\dfrac{11}{3}\)
giúp mik vs ạ mik cần gấp
tìm x:
a) \(x-\frac{5}{7}-\frac{13}{14}=1\) b) \(\frac{3}{5}+x+1\frac{1}{5}=\frac{11}{3}\)
3 x ( 1/7 + 1/3 - 3/14 ) : 11/14
( 8/5 + 11/5 ) x 11/10 + ( 17/10 - 4/5) : 3/7
3/14 +5/8 -1/3
1/4-2/3 :11/8
1/4 + 5/12 -1/13 -7/8
Bài 2 : Tìm x
A. 4/7 * x - 2/3 = 1/5
B. 7/9 -2/9 * x =1/3
C. 4/5 +5/7 : x =1/6
Giúp mìnhh nha
tinh bang cach thuan tien 3/5 x 7/9 + 11/9 x 3/5 - 3/10. B 14/13 : 1/2 + 3/13 x2 -2 x 7/13
1.Tính
\(a,5\text{x}\dfrac{7}{3}\) \(b,\dfrac{13}{4}:7\)
2.Tính
\(a,\dfrac{3}{7}+\dfrac{2}{5}+\dfrac{3}{4}\) \(b,\dfrac{9}{7}-\dfrac{5}{11}\text{x}\dfrac{11}{7}\) \(c,\dfrac{3}{5}\text{x}\dfrac{5}{7}\text{+}\dfrac{4}{7}\) \(d,\dfrac{7}{9}\text{x}\dfrac{2}{5}:\dfrac{3}{11}\) e,\(\dfrac{9}{7}+\dfrac{2}{3}-\dfrac{1}{4}\)
g,\(\dfrac{4}{9}:\dfrac{3}{5}\text{x}\dfrac{2}{11}\) h,\(\dfrac{7}{2}-\dfrac{3}{10}:\dfrac{2}{5}\)
tìm x:
a) \(x-\frac{5}{7}-\frac{13}{14}=1\) b) \(\frac{3}{5}+x+1\frac{1}{5}=\frac{11}{3}\) c) \(x.\frac{4}{5}:2=\frac{6}{7}\) d) \(\frac{6}{5}:x:\frac{5}{4}=\frac{10}{15}\)
