Solve the inequality

Answer

Graph

$- 3 x < 15$

Solution of inequality

$x > - 5$

$-3x < 15$

$x > - 5$

$ $ Solve a solution to $ x$

$\color{#FF6800}{ - } \color{#FF6800}{ 3 } \color{#FF6800}{ x } < \color{#FF6800}{ 15 }$

$ $ Change the symbol of the inequality of both sides, and reverse the symbol of the inequality to the opposite direction $ $

$3 x > - 15$

$\color{#FF6800}{ 3 } \color{#FF6800}{ x } > \color{#FF6800}{ - } \color{#FF6800}{ 15 }$

$ $ Divide both sides by the same number $ $

$\color{#FF6800}{ x } > \color{#FF6800}{ - } \color{#FF6800}{ 5 }$
