Answer: x=-2

Explanation:

addition property of equality is adding the same number to both sides of an equation does not change the equation.

distributive property: a(b+c)=ab+ac

add 3 both sides of an equation.

6x-3+3=3x-9+3

simplify an equation

6x=3x-6

subtract 3x both sides of an equation

6x-3x=3x-6-3x

simplify

3x=-6

divide 3 both sides of an equation

3x/3=-6/3

simplify

-6/3=-2

the answer should be the negative sign.

x=-2

Hope this helps!

Thanks!
