Question

Solve the inequality:

Answer 1

Answer:

z ≤ -2

Explanation:

3z − 1 ≤ -7

3z ≤ -6

z ≤ -2

Answer 2

Answer:

$z \leqslant - 2$

Step-by-step explanation:

1) Add 1 to both sides.

$3z \leqslant - 7 + 1$

2) Simplify -7 + 1 to -6.

$3z \leqslant - 6$

3) Divide both sides by 3.

$z \leqslant - \frac{6}{3}$

4) Simplify 6/3 to 2.

$z \leqslant - 2$

Therefor, the answer is Option C.
