60% x+0.4x+x:3=2

Answer 1

\(60\%x+0,4.x+\frac{x}{3}=2\)

\(\frac{3}{5}.x+\frac{2}{5}.x+\frac{1}{3}.x=2\)

\(x.\left(\frac{3}{5}+\frac{2}{5}+\frac{1}{3}\right)=2\)

\(x.\frac{4}{3}=2\)

\(x=2:\frac{4}{3}\)

\(x=\frac{3}{2}=1,5\)

Answer 2

60% x + 0,4x + x : 3 = 2

3/5 . x + 2/5 . x + x : 3 = 2

(3/5 + 2/5) x + x : 3 = 2

x + x : 3 = 2

x : (1 + 3) = 2

x : 4 = 2

x = 8

Answer 3

60% x + 0,4 x + x : 3 = 2

3/5 . x + 2/5 . x + x : 3 = 2

x . ( 3/5 + 2/5 ) + x : 3 =2

x . ( 1+ 1/3) = 2

x . 4/3 = 2

x = 2 : 4/3

x = 3/2
