Question

Solve:

-1 ≤ 3z + 2 ≤ 8

Answer 1

Let's do this! First, we'll make this a bit easier by subtracting two from each of the sides so that 3z is cozy by itself in the middle, giving us
\[−3≤3z≤6\]
Then, we just divide each side by 3 to get z by itself. A bit lonely, but in the name of progress! This finally gives us..
\[−1≤z≤2\]
Happy Homework!
