Question

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

\(b.1\frac{8}{15}-\frac{2}{3}x=0,2\)

\(c.\frac{2}{3}x-\frac{3}{2}x=\frac{5}{12}\)

Answer 1

a.2/3 + 1/3 - x= 3/5

=> 1-x = 3/5

=>  x = 1-3/5= 2/5

b. 1/8/15 - 2/3x = 0,2

=> 2/3x= 23/15 - 1/5= 4/3

=> x= 4/3 : 2/3=2

c. 2/3x -3/2x = 5/12

=> x( 2/3 - 3/2) = 5/12

=> x. -5/6 = 5/12

=> x= 5/12 : -5/6

=> x= -1/2

Answer 2

a) 2/3 + 1/3 - x = 3/5

=> 1 - x = 3/5

=> x = 1 - 3/5

     x = 2/5

b) \(1\frac{8}{15}-\frac{2}{3}x=0,2\)

=> 23/15 - 2/3x = 0,2

=> 2/3x = 23/15 - 0,2

    2/3x = 1,333333333

=>x = 1,333333333 : 2/3

    x = 2

c) ???
