Answer:
[tex]\huge\boxed{x=1}[/tex]
Step-by-step explanation:
When simplifying down an expression, our goal is to isolate the variable (x) on one side by reversing the equation.
Apply the distributive property on the left and right side:
[tex]6 -6x + 12 = 9x + 3[/tex]
Combine like terms on the left side:
[tex]-6x+18 = 9x + 3[/tex]
Add 6x to both sides:
[tex]18 = 15x+3[/tex]
Subtract 3 from both sides:
[tex]15=15x[/tex]
Divide both sides by 15:
[tex]1=x\\x=1[/tex]
