$y = 3 + 4$
$y = x \div \dfrac { 1 } { 3 }$
$x$Intercept
$\left ( 0 , 0 \right )$
$y$Intercept
$\left ( 0 , 0 \right )$
$3+4 = x \div \dfrac{ 1 }{ 3 }$
$x = \dfrac { 7 } { 3 }$
$ $ Solve a solution to $ x$
$\color{#FF6800}{ 3 } \color{#FF6800}{ + } \color{#FF6800}{ 4 } = x \div \dfrac { 1 } { 3 }$
$ $ Add $ 3 $ and $ 4$
$\color{#FF6800}{ 7 } = x \div \dfrac { 1 } { 3 }$
$7 = \color{#FF6800}{ x } \color{#FF6800}{ \div } \color{#FF6800}{ \dfrac { 1 } { 3 } }$
$ $ Calculate the multiplication expression $ $
$7 = \color{#FF6800}{ 3 } \color{#FF6800}{ x }$
$7 = \color{#FF6800}{ 3 } \color{#FF6800}{ x }$
$ $ Move the variable to the left-hand side and change the symbol $ $
$7 \color{#FF6800}{ - } \color{#FF6800}{ 3 } \color{#FF6800}{ x } = 0$
$\color{#FF6800}{ 7 } - 3 x = 0$
$ $ Move the constant to the right side and change the sign $ $
$- 3 x = \color{#FF6800}{ - } \color{#FF6800}{ 7 }$
$\color{#FF6800}{ - } \color{#FF6800}{ 3 } \color{#FF6800}{ x } = \color{#FF6800}{ - } \color{#FF6800}{ 7 }$
$ $ Change the sign of both sides of the equation $ $
$3 x = 7$
$\color{#FF6800}{ 3 } \color{#FF6800}{ x } = \color{#FF6800}{ 7 }$
$ $ Divide both sides by the same number $ $
$\color{#FF6800}{ x } = \color{#FF6800}{ \dfrac { 7 } { 3 } }$
