What is the range of values of $x$ that satisfies the inequality $3 - 2x > 9$ ?

x < -3

Subtracting 3 from both sides yields

-2x > 6

. Dividing both sides by

-2

and reversing the inequality symbol gives

x < -3

Subtract 3 from both sides of the inequality.

-2x > 6

To isolate the variable term

-2x

on the left-hand side.

Divide both sides by

-2

and reverse the inequality sign.

x < -3

Dividing an inequality by a negative number requires reversing the direction of the inequality sign.
