$\left ( 0 , 12 \right )$
$8x-15 = 2 \left( x+6 \right)$
$x = \dfrac { 9 } { 2 }$
$ $ Solve a solution to $ x$
$8 x - 15 = \color{#FF6800}{ 2 } \left ( \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 6 } \right )$
$ $ Multiply each term in parentheses by $ 2$
$8 x - 15 = \color{#FF6800}{ 2 } \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 2 } \color{#FF6800}{ \times } \color{#FF6800}{ 6 }$
$8 x - 15 = 2 x + \color{#FF6800}{ 2 } \color{#FF6800}{ \times } \color{#FF6800}{ 6 }$
$ $ Multiply $ 2 $ and $ 6$
$8 x - 15 = 2 x + \color{#FF6800}{ 12 }$
$8 x - 15 = \color{#FF6800}{ 2 } \color{#FF6800}{ x } + 12$
$ $ Move the variable to the left-hand side and change the symbol $ $
$8 x - 15 \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ x } = 12$
$8 x \color{#FF6800}{ - } \color{#FF6800}{ 15 } - 2 x = 12$
$ $ Move the constant to the right side and change the sign $ $
$8 x - 2 x = 12 \color{#FF6800}{ + } \color{#FF6800}{ 15 }$
$\color{#FF6800}{ 8 } \color{#FF6800}{ x } \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ x } = 12 + 15$
$ $ Organize the expression $ $
$\color{#FF6800}{ 6 } \color{#FF6800}{ x } = 12 + 15$
$6 x = \color{#FF6800}{ 12 } \color{#FF6800}{ + } \color{#FF6800}{ 15 }$
$ $ Add $ 12 $ and $ 15$
$6 x = \color{#FF6800}{ 27 }$
$\color{#FF6800}{ 6 } \color{#FF6800}{ x } = \color{#FF6800}{ 27 }$
$ $ Divide both sides by the same number $ $
$\color{#FF6800}{ x } = \color{#FF6800}{ \dfrac { 9 } { 2 } }$
