$y = 2 x + 1$
$y = x$
$x$Intercept
$\left ( - \dfrac { 1 } { 2 } , 0 \right )$
$y$Intercept
$\left ( 0 , 1 \right )$
$x$Intercept
$\left ( 0 , 0 \right )$
$y$Intercept
$\left ( 0 , 0 \right )$
$2x+1 = x$
$x = - 1$
$ $ Solve a solution to $ x$
$2 x + 1 = \color{#FF6800}{ x }$
$ $ Move the variable to the left-hand side and change the symbol $ $
$2 x + 1 \color{#FF6800}{ - } \color{#FF6800}{ x } = 0$
$2 x \color{#FF6800}{ + } \color{#FF6800}{ 1 } - x = 0$
$ $ Move the constant to the right side and change the sign $ $
$2 x - x = \color{#FF6800}{ - } \color{#FF6800}{ 1 }$
$\color{#FF6800}{ 2 } \color{#FF6800}{ x } \color{#FF6800}{ - } \color{#FF6800}{ x } = - 1$
$ $ Organize the expression $ $
$\color{#FF6800}{ x } = - 1$
