Hello.

In order to solve this equation, we need to isolate the variable (in this case, the variable is x)

The first step is to use the Distributive Property and distribute 3:

$\mathrm{3(x-1)=2x+9}$

$\mathrm{3x-3=2x+9}$

Now, add 3 to both sides:

$\mathrm{3x-3+3=2x+9+3}$

$\mathrm{3x=2x+9+3}$

$\mathrm{3x=2x+12}$

Now, subtract 2x from both sides:

$\mathrm{3x-2x=2x-2x+12}\\\mathrm{3x-2x=12}$

$\mathrm{x=12}$

Therefore, the answer is

$\mathrm{x=12}$

I hope it helps.

Have a nice day.
