\(60\%.x-0,4.x+x:3=2\)
\(\dfrac{3}{5}.x-\dfrac{2}{5}.x+\dfrac{1}{3}.x=2\)
\(x\left(\dfrac{3}{5}-\dfrac{2}{5}+\dfrac{1}{3}\right)=2\)
\(x.\dfrac{8}{15}=2\)
\(x=2:\dfrac{8}{15}\)
\(x=\dfrac{15}{4}\)

60%x+0,4x+x:3=2
\(\frac{60}{100}+x\frac{2}{5}+x:3=2\)
\(x.\left(\frac{3}{5}+\frac{2}{5}\right)+x:3=2\)
\(x.1+x:3=2\)
\(x.2=\left(3:1\right)\)
\(x.2=3\)
\(x=3:2\)
\(x=1,5\)

\(x:60\%+0,4x=2\)
\(\Rightarrow\dfrac{5}{3}x+0,4x=2\)
\(\Rightarrow\left(\dfrac{5}{3}+0,4\right)x=2\)
\(\Rightarrow\dfrac{31}{15}x=2\)
\(\Rightarrow x=2:\dfrac{31}{15}\)
\(\Rightarrow x=\dfrac{30}{31}\)

60% + 0,4x=2
0,4x=2-60%
0,4x=2-0,6
0,4x=1,4
x=1,4:0,4
x=3,5
Vậy:...

\(60\%x+0,4x+x:3=2\)
\(\Leftrightarrow\frac{3}{5}x+\frac{2}{5}x+\frac{1}{3}x=2\)
\(x\left(\frac{3}{5}+\frac{2}{5}+\frac{1}{4}\right)=2\)
\(x.\frac{4}{3}=2\)
\(x=2:\frac{4}{3}\)
\(x=\frac{3}{2}\)
60%x + 0,4x + x:3 = 2
\(\frac{3}{5}x+\frac{2}{5}x+\frac{1}{3}x=2\)
\(\left(\frac{3}{5}+\frac{2}{5}+\frac{1}{3}\right)x=2\)
\(\frac{4}{3}x=2\)
\(x=2:\frac{4}{3}\)
\(x=\frac{3}{2}\)
bạn đỏi ra đi, rồi lấy thừa số mà tính
