Step-by-step explanation

To solve the given inequality, we will have


3|x-4|-5<10

To solve the question

we will follow the steps below

Step 1:


\begin{gathered} \mathrm{Add\:}5\mathrm{\:to\:both\:sides} \\ 3\left|x-4\right|-5+5<10+5 \end{gathered}

Step 2:


\begin{gathered} \mathrm{Simplify} \\ 3\left|x-4\right|<15 \end{gathered}

Step 3:


\begin{gathered} \mathrm{Divide\:both\:sides\:by\:}3 \\ (3\left|x-4\right|)/(3)<(15)/(3) \end{gathered}

Step 4:


\begin{gathered} \mathrm{Simplify} \\ \left|x-4\right|<5 \end{gathered}

step 5


\begin{gathered} \mathrm{Apply\:absolute\:rule}:\quad \mathrm{If}\:|u|\:<\:a,\:a>0\:\mathrm{then}\:-a\:<\:u\:<\:a \\ -5Step 6[tex]x>-1\quad \mathrm{and}\quad \:x<9

Thus we have the answer as
