solution set of -3x + 9 < 3?

Sagot :

Answer:

The solution to the inequality is;

[tex]\begin{gathered} x>2 \\ x=(2,\infty) \end{gathered}[/tex]

Explanation:

Given the inequality;

[tex]-3x+9<3[/tex]

to solve the inequality, firstly, let's subtract 9 from both sides;

[tex]\begin{gathered} -3x+9-9<3-9 \\ -3x<-6 \end{gathered}[/tex]

Then we can now divide both sides by -3. (note that dividing by a negative number will affect the inequality sign);

[tex]\begin{gathered} \frac{-3x}{-3}>\frac{-6}{-3} \\ x>2 \end{gathered}[/tex]

Therefore, the solution to the inequality is;

[tex]\begin{gathered} x>2 \\ x=(2,\infty) \end{gathered}[/tex]
