Formula

Solve the equation

Answer

Graph

$y = 6 + x$

$y = 3 x$

$x$Intercept

$\left ( - 6 , 0 \right )$

$y$Intercept

$\left ( 0 , 6 \right )$

$x$Intercept

$\left ( 0 , 0 \right )$

$y$Intercept

$\left ( 0 , 0 \right )$

$6+x = 3x$

$x = 3$

$ $ Solve a solution to $ x$

$\color{#FF6800}{ 6 } \color{#FF6800}{ + } \color{#FF6800}{ x } = 3 x$

$ $ Organize the expression $ $

$\color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 6 } = 3 x$

$x + 6 = \color{#FF6800}{ 3 } \color{#FF6800}{ x }$

$ $ Move the variable to the left-hand side and change the symbol $ $

$x + 6 \color{#FF6800}{ - } \color{#FF6800}{ 3 } \color{#FF6800}{ x } = 0$

$x \color{#FF6800}{ + } \color{#FF6800}{ 6 } - 3 x = 0$

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

$x - 3 x = \color{#FF6800}{ - } \color{#FF6800}{ 6 }$

$\color{#FF6800}{ x } \color{#FF6800}{ - } \color{#FF6800}{ 3 } \color{#FF6800}{ x } = - 6$

$ $ Organize the expression $ $

$\color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ x } = - 6$

$\color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ x } = \color{#FF6800}{ - } \color{#FF6800}{ 6 }$

$ $ Change the sign of both sides of the equation $ $

$2 x = 6$

$\color{#FF6800}{ 2 } \color{#FF6800}{ x } = \color{#FF6800}{ 6 }$

$ $ Divide both sides by the same number $ $

$\color{#FF6800}{ x } = \color{#FF6800}{ 3 }$
