Solve the following inequality using an algebraic approach:

-4 < 3x+5 less than or equal to 11

Can you explain how you got this answer?

Answer 1

\[-4 < 3x + 5 \le 11\]
split into two
\[-4 < 3x + 5\]
and
\[3x + 5 \le 11\]

Solve, then put back together again

Answer 2

-4 < 3x+5<= 11

-5 -5 -5

-9 < 3x <= 4

/3 /3 /3

-3 < x <= 4/3

Answer 3

I don't really know what you mean by algebraic approach precisely.
