Answer: 1. {-10}
Step-by-step explanation:
To find the solution you have to isolate the variable x in the equation.
First, using the distributive property, you do the multiplication to get rid of the parentheses:
[tex]x-3-2(x+6)=-5\\x-3-2x-12=-5[/tex]
Then, you combine like terms across the equal sign, changing the sign as you move them from one side to the other, and finally you solve:
[tex]x-2x=-5+3+12\\-x=10\\x=-10[/tex]
