$7- \dfrac{ a }{ 2 } = 2$
$a = 10$
$ $ Solve a solution to $ a$
$\color{#FF6800}{ 7 } \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { a } { 2 } } = \color{#FF6800}{ 2 }$
$ $ Multiply both sides by the least common multiple for the denominators to eliminate the fraction $ $
$\color{#FF6800}{ 14 } \color{#FF6800}{ - } \color{#FF6800}{ a } = \color{#FF6800}{ 4 }$
$\color{#FF6800}{ 14 } - a = 4$
$ $ Move the constant to the right side and change the sign $ $
$- a = 4 \color{#FF6800}{ - } \color{#FF6800}{ 14 }$
$- a = \color{#FF6800}{ 4 } \color{#FF6800}{ - } \color{#FF6800}{ 14 }$
$ $ Subtract $ 14 $ from $ 4$
$- a = \color{#FF6800}{ - } \color{#FF6800}{ 10 }$
$\color{#FF6800}{ - } \color{#FF6800}{ a } = \color{#FF6800}{ - } \color{#FF6800}{ 10 }$
$ $ Change the sign of both sides of the equation $ $
$\color{#FF6800}{ a } = \color{#FF6800}{ - } \left ( \color{#FF6800}{ - } \color{#FF6800}{ 10 } \right )$
$a = \color{#FF6800}{ - } \left ( \color{#FF6800}{ - } 10 \right )$
$ $ Simplify Minus $ $
$a = 10$
