$x= -10$

First, subtract $20$ from both sides of the equation so that the right side of the equation only has one term. This will give you

$-20+x=3x$

Next, subtract $x$ from both sides so that only one side has a variable. Now you should have

$-20=2x$

The last step is to divide both sides of the equation by $2$ , which will give you

$-10=x$

You can double check to see if this is the solution by substituting $x$ with $-10$ in the original equation.
