10/3 x 1/2 - ( 1/2 x X - 1/3) + 1/5 = 3/5 :1/2
5/3 - ( 1/2 x X - 1/3) + 1/5 = 6/5
5/3 - ( 1/2 x X - 1/3) = 6/5 + 1/5
5/3 - ( 1/2 x X - 1/3) = 7/5
1/2 x X - 1/3 = 5/3 - 7/5
1/2 x X - 1/3 = 4/15
1/2 x X = 4/15 + 1/3
1/2 x X = 9/15
X = 9/15 : 1/2
X = 18/15.
[(x+1/3)+1/6]-1/2:2=3/4
=>[x+1/3+1/6]-1/4=3/4
=>x+1/2=3/4+1/4=1
=>x=1-1/2=1/2
\(\left[\left(x\times\frac{1}{3}\right)+\frac{1}{6}\right]-\frac{1}{2}\div2=\frac{3}{4}\)
\(\left[\left(x\times\frac{1}{3}\right)+\frac{1}{6}\right]-\frac{1}{2}=\frac{3}{4}\times2\)
\(\left[\left(x\times\frac{1}{3}\right)+\frac{1}{6}\right]-\frac{1}{2}=\frac{3}{2}\)
\(\left(x\times\frac{1}{3}\right)+\frac{1}{6}=\frac{3}{2}+\frac{1}{2}\)
\(\left(x\times\frac{1}{3}\right)+\frac{1}{6}=2\)
\(x\times\frac{1}{3}=2-\frac{1}{6}\)
\(x\times\frac{1}{3}=\frac{11}{6}\)
\(x=\frac{11}{6}\div\frac{1}{3}\)
\(\Rightarrow x=\frac{11}{2}\)
(x/2-1/3).5/6-1/2=1/3
=>(x/2-1/3).5/6=1/3+1/2=5/6
=>x/2-1/3=5/6:5/6=1
=>x/2=1+1/3=4/3
=>x=4/3.2=8/3
vậy x=8/3
( x/2 - 1/3 ) . 5/6 - 1/2 = 1/3
( x/2 - 1/3 ) . 5/6 = 1/3 + 1/2
( x/2 - 1/3 ) . 5/6 = 5/6
( x/2 - 1/3 ) = 5/6 : 5/6
( x/2 - 1/3 ) = 1
x/2 = 1 + 1/3
x/2 = 4/3
x = 4/3 : 2
x = 2/3
Viết cái đề cho rõ ràng dùm cái, mk đọc ko có hỉu j hết
\(3-\left(2x+\frac{1}{2}\right)\div\frac{1}{2}=2\)
\(\Leftrightarrow\left(2x+\frac{1}{2}\right)\div\frac{1}{2}=3-2\)
\(\Leftrightarrow\left(2x+\frac{1}{2}\right)\times2=1\)
\(\Leftrightarrow2x+\frac{1}{2}=\frac{1}{2}\)
\(\Leftrightarrow2x=\frac{1}{2}-\frac{1}{2}\)
\(\Leftrightarrow2x=0\)
\(\Leftrightarrow x=0\div2\)
\(\Leftrightarrow x=0\)
Vậy x = 0
\(3-\left(x\times2+\frac{1}{2}\right):\frac{1}{2}=2\)
\(\left(x\times2+\frac{1}{2}\right):\frac{1}{2}=3-2\)
\(\left(x\times2+\frac{1}{2}\right):\frac{1}{2}=1\)
\(x\times2+\frac{1}{2}=1\times\frac{1}{2}\)
\(x\times2+\frac{1}{2}=\frac{1}{2}\)
\(x\times2=\frac{1}{2}-\frac{1}{2}\)
\(x\times2=0\)
x = 0 : 2
x = 0
Vậy x = 0
