Question

15)Solve each equation or inequality. Write solutions to inequalities in interval notation. If no solutions exist, write no solution.

Answer 1

Given:

`\text{ lx-6l}\leq15`

Required:

We need to write solutions to inequalities in interval notation.

Step-by-step explanation:

`\text{lx-6l}\leqslant15`

now open mode

`-15\leq\text{x-6}\leqslant15`

now add 6 every sides

`\begin{gathered} -15+6\leqslant x-6+6\leqslant15+6 \\ -9\leq x\leq21 \end{gathered}`

Final answer:

Interval of solution is [-9,21]
