Answer 2

3/5x + 2/5 = 2

3/5x = 2-2/5

3/5x = 8/5

x=8/5:3/5

x=8/3

Answer 4

3/5x+0,4=2

3/5x+2/5=2

3/5x= 2-2/5

3/5x=8/5

x=8/5:3/5

x=8/3

Answer 5

3/5x+0,4=2

3/5x+2/5=2

3/5x       =2-2/5

3/5x        =10/5-2/5

3/5x        =8/5

    x         =8/5 : 3/5

    x         =8/5 . 5/3

    x        =8/3

Answer 6

\(\frac{3}{5}x+0.4=2\)

\(\frac{3}{5}x=2-0.4\)

\(x=1.6:\frac{3}{5}\)

\(x=\frac{8}{3}\)
