$5x-5 = 2x+16 =$
$x = 7$
$ $ Solve a solution to $ x$
$5 x - 5 = \color{#FF6800}{ 2 } \color{#FF6800}{ x } + 16$
$ $ Move the variable to the left-hand side and change the symbol $ $
$5 x - 5 \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ x } = 16$
$5 x \color{#FF6800}{ - } \color{#FF6800}{ 5 } - 2 x = 16$
$ $ Move the constant to the right side and change the sign $ $
$5 x - 2 x = 16 \color{#FF6800}{ + } \color{#FF6800}{ 5 }$
$\color{#FF6800}{ 5 } \color{#FF6800}{ x } \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ x } = 16 + 5$
$ $ Organize the expression $ $
$\color{#FF6800}{ 3 } \color{#FF6800}{ x } = 16 + 5$
$3 x = \color{#FF6800}{ 16 } \color{#FF6800}{ + } \color{#FF6800}{ 5 }$
$ $ Add $ 16 $ and $ 5$
$3 x = \color{#FF6800}{ 21 }$
$\color{#FF6800}{ 3 } \color{#FF6800}{ x } = \color{#FF6800}{ 21 }$
$ $ Divide both sides by the same number $ $
$\color{#FF6800}{ x } = \color{#FF6800}{ 7 }$
