$4a+5 = 13$
$a = 2$
$ $ Solve a solution to $ a$
$4 a \color{#FF6800}{ + } \color{#FF6800}{ 5 } = 13$
$ $ Move the constant to the right side and change the sign $ $
$4 a = 13 \color{#FF6800}{ - } \color{#FF6800}{ 5 }$
$4 a = \color{#FF6800}{ 13 } \color{#FF6800}{ - } \color{#FF6800}{ 5 }$
$ $ Subtract $ 5 $ from $ 13$
$4 a = \color{#FF6800}{ 8 }$
$\color{#FF6800}{ 4 } \color{#FF6800}{ a } = \color{#FF6800}{ 8 }$
$ $ Divide both sides by the same number $ $
$\color{#FF6800}{ a } = \color{#FF6800}{ 2 }$
