Solve for x by simplifying both sides of the equation, then isolating the variable.
x = -10

Answer: 1. {-10}

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:


x-3-2(x+6)=-5\\x-3-2x-12=-5

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:


x-2x=-5+3+12\\-x=10\\x=-10
