Question

Solve 3x+9 so it has no solution.

Answer 1

Answer:

x = -3

Step-by-step 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
