Answer:
x = -3
Explanation:
I hope you mean "no solution" as in 'equal to zero' because that's what I'm doing and what makes sense.
Start by setting the equation equal to zero.
3x + 9 = 0
Subtract the 9 from both sides to move it to the right side.
3x = -9
Divide the 3 from both sides to isolate the x.
x = -3
We can check that x = -3 is the correct answer by plugging it in and seeing if it equals zero.
3(-3) + 9
-9 + 9
0
