Understanding:

The sum of 3 times a number (i'll define it as x) and 4 means $3x+4$ is between -8 and 10 which means the value of 3x+4 is less than 10 and greater than -8. With that said, the inequality for that problem would be $-8$ .

Solving the problem:

Now we know that $-8$ , you can solve the problem by subtracting 4 from each side then dividing by 3.

$-8-4$

Final Answer:

$-4$
