3x+6=0 what is the value of x?

3x+6=0
3x =-6
x = -6/3 =-2
x =-2

3x + 6 = 0
3x = -6
x = -6/3
x = -2

x = - 2

x=-2

3 x -2 = -6

-6 +6 = 0

-2

3x + 6 = 0
3x = -6
x = -2

In this equation you can take 6 on the other side but it will change its sign so you will get

3x = -6

now divide both sides by 3 to get

x = -2

3x = -6

X= -6/3

X = -2

You can also just get a scientific calculator and it does the work for you. We use it at our school, Algebra is so easy with it.

3x+6 -6 = -6
3x/3 = -6/3
x=-2
