$\color{#FF6800}{ 0.3 } \color{#FF6800}{ x } - 0.4 = 0.2 x - 0.6$
$ $ Calculate the multiplication expression $ $
$\color{#FF6800}{ \dfrac { 3 x } { 10 } } - 0.4 = 0.2 x - 0.6$
$\dfrac { 3 x } { 10 } \color{#FF6800}{ - } \color{#FF6800}{ 0.4 } = 0.2 x - 0.6$
$ $ Convert decimals to fractions $ $
$\dfrac { 3 x } { 10 } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 2 } { 5 } } = 0.2 x - 0.6$
$\dfrac { 3 x } { 10 } - \dfrac { 2 } { 5 } = \color{#FF6800}{ 0.2 } \color{#FF6800}{ x } - 0.6$
$ $ Calculate the multiplication expression $ $
$\dfrac { 3 x } { 10 } - \dfrac { 2 } { 5 } = \color{#FF6800}{ \dfrac { x } { 5 } } - 0.6$
$\dfrac { 3 x } { 10 } - \dfrac { 2 } { 5 } = \dfrac { x } { 5 } \color{#FF6800}{ - } \color{#FF6800}{ 0.6 }$
$ $ Convert decimals to fractions $ $
$\dfrac { 3 x } { 10 } - \dfrac { 2 } { 5 } = \dfrac { x } { 5 } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 3 } { 5 } }$
$\color{#FF6800}{ \dfrac { 3 x } { 10 } } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 2 } { 5 } } = \color{#FF6800}{ \dfrac { x } { 5 } } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 3 } { 5 } }$
$ $ Multiply both sides by the least common multiple for the denominators to eliminate the fraction $ $
$\color{#FF6800}{ 3 } \color{#FF6800}{ x } \color{#FF6800}{ - } \color{#FF6800}{ 4 } = \color{#FF6800}{ 2 } \color{#FF6800}{ x } \color{#FF6800}{ - } \color{#FF6800}{ 6 }$
$3 x - 4 = \color{#FF6800}{ 2 } \color{#FF6800}{ x } - 6$
$ $ Move the variable to the left-hand side and change the symbol $ $
$3 x - 4 \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ x } = - 6$
$3 x \color{#FF6800}{ - } \color{#FF6800}{ 4 } - 2 x = - 6$
$ $ Move the constant to the right side and change the sign $ $
$3 x - 2 x = - 6 \color{#FF6800}{ + } \color{#FF6800}{ 4 }$
$\color{#FF6800}{ 3 } \color{#FF6800}{ x } \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ x } = - 6 + 4$
$ $ Organize the expression $ $
$\color{#FF6800}{ x } = - 6 + 4$
$x = \color{#FF6800}{ - } \color{#FF6800}{ 6 } \color{#FF6800}{ + } \color{#FF6800}{ 4 }$
$ $ Add $ - 6 $ and $ 4$
$x = \color{#FF6800}{ - } \color{#FF6800}{ 2 }$
