Solve the equation

Answer

$$2 x + 1 = 3$$

$x = 1$

$ $ Solve a solution to $ x$

$2 x \color{#FF6800}{ + } \color{#FF6800}{ 1 } = 3$

$ $ Move the constant to the right side and change the sign $ $

$2 x = 3 \color{#FF6800}{ - } \color{#FF6800}{ 1 }$

$2 x = \color{#FF6800}{ 3 } \color{#FF6800}{ - } \color{#FF6800}{ 1 }$

$ $ Subtract $ 1 $ from $ 3$

$2 x = \color{#FF6800}{ 2 }$

$\color{#FF6800}{ 2 } \color{#FF6800}{ x } = \color{#FF6800}{ 2 }$

$ $ Divide both sides by the same number $ $

$\color{#FF6800}{ x } = \color{#FF6800}{ 1 }$
