What do you think should be the first step?
We want to get x on one side of the equation all by itself so that the answer looks like
x=?
13+2x=3
How can we remove the 13?
What would happen if we added 13 to both sides?
Would the original 13 go away?
What would make the 13 go away?

You must isolate x on one side of the equation. To do this, you will subtract 13 from both sides of the equation.
So,
13 + 2x = 3
-13 + 13 + 2x = 3 - 13
2x = -10
Now you will divide both sides by 2 to get x by itself.
2x/2 = -10/2
x = -5
