INFORMATION:

We have the following inequality

[tex]3x+9\leq15[/tex]

And we must solve it

STEP BY STEP EXPLANATION:

To solve it, we must:

1. Subtract 9 from both sides

[tex]\begin{gathered} 3x+9-9\leq15-9 \\ 3x\leq6 \end{gathered}[/tex]

2. Divide both sides by 3

[tex]\frac{3x}{3}\leq\frac{6}{3}[/tex]

3. Simplify

[tex]x\leq2[/tex]

Finally, the solution of the inequality is x ≤ 2

ANSWER:

The solution for 3x + 9 ≤ 15 is x ≤ 2
