Question

I need help on this. I don't really understand this question. I kinda confused about this question

Answer 1

The given expression is

$-4t-5>7$

First, we add 5 on each side

$\begin{gathered} -4t-5+5>7+5 \\ -4t>12 \end{gathered}$

Then, we divide the equation by -4

$\begin{gathered} \frac{-4t}{-4}<\frac{12}{-4} \\ t<-3 \end{gathered}$

The image below shows this solution.

Hence, the answer is B.
