Answer 1

60%.x -x+1/3=2

<=> -40%x=5/3

<=>x=5/3 : (-40%)

<=>x=-25/6

Answer 2

a) 60% . x - x + \(\dfrac{1}{3}\) = 2

\(\Rightarrow\) \(\left(\dfrac{3}{5}-1\right)\)x = \(\dfrac{5}{3}\)

\(\Rightarrow\) \(\dfrac{-2}{5}\)x = \(\dfrac{5}{3}\)

\(\Rightarrow\) x = \(\dfrac{-25}{6}\)

Answer 3

\(x=-\dfrac{25}{6}\)
