x= -10
first you distribute the -2 throughout (x+6) which then becomes, -2x -12
After you’ve done that plug it in the equation, the equation should be, x-3-2x-12=-5
Now combine like terms. After it should look like, -x - 15 = -5, Add 15 to both side. It should be, -x = 10
Finally divide by -1 on both sides and that should give you x= -10
sorry that was a long explanation
