Solve the inequality
Graph
$3 \left ( 2 - x \right ) + 4 \leq 1$
$3 \left ( 2 - x \right ) + 4 \leq 1$
Solution of inequality
$x \geq 3$
$3 \left( 2-x \right) +4 \leq 1$
$x \geq 3$
 Solve a solution to $x$
$\color{#FF6800}{ 3 } \left ( \color{#FF6800}{ 2 } \color{#FF6800}{ - } \color{#FF6800}{ x } \right ) + 4 \leq 1$
 Multiply each term in parentheses by $3$
$\color{#FF6800}{ 3 } \color{#FF6800}{ \times } \color{#FF6800}{ 2 } \color{#FF6800}{ - } \color{#FF6800}{ 3 } \color{#FF6800}{ x } + 4 \leq 1$
$\color{#FF6800}{ 3 } \color{#FF6800}{ \times } \color{#FF6800}{ 2 } - 3 x + 4 \leq 1$
 Multiply $3$ and $2$
$\color{#FF6800}{ 6 } - 3 x + 4 \leq 1$
$\color{#FF6800}{ 6 } - 3 x \color{#FF6800}{ + } \color{#FF6800}{ 4 } \leq 1$
 Add $6$ and $4$
$\color{#FF6800}{ 10 } - 3 x \leq 1$
$\color{#FF6800}{ 10 } \color{#FF6800}{ - } \color{#FF6800}{ 3 } \color{#FF6800}{ x } \leq 1$
 Organize the expression 
$\color{#FF6800}{ - } \color{#FF6800}{ 3 } \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 10 } \leq 1$
$- 3 x \color{#FF6800}{ + } \color{#FF6800}{ 10 } \leq 1$
 Move the constant to the right side and change the sign 
$- 3 x \leq 1 \color{#FF6800}{ - } \color{#FF6800}{ 10 }$
$- 3 x \leq \color{#FF6800}{ 1 } \color{#FF6800}{ - } \color{#FF6800}{ 10 }$
 Subtract $10$ from $1$
$- 3 x \leq \color{#FF6800}{ - } \color{#FF6800}{ 9 }$
$\color{#FF6800}{ - } \color{#FF6800}{ 3 } \color{#FF6800}{ x } \leq \color{#FF6800}{ - } \color{#FF6800}{ 9 }$
 Change the symbol of the inequality of both sides, and reverse the symbol of the inequality to the opposite direction 
$3 x \geq 9$
$\color{#FF6800}{ 3 } \color{#FF6800}{ x } \geq \color{#FF6800}{ 9 }$
 Divide both sides by the same number 
$\color{#FF6800}{ x } \geq \color{#FF6800}{ 3 }$
