The answer is x = -4. Applying the square root property of equality basically means that we need to take the square roots of both sides.

Which turns into:

Then we can isolate x by subtracting 9 from both sides:
Answer:
x ≤ 4
Step-by-step explanation:
6x + 3 ≤ 27 subtract 3 both sides
6x ≤ 24 divide 6 both sides
x ≤ 4 There's your answer
Answer:

Step-by-step explanation:
