1 - 2x - 1 =-10
Subtract 1 from both sides
-2x - 1= -11
Add 1 to both sides
-2x= -10
Divide both sides by -2 so that the only thing remaining on the left side is the variable x.
Final Answer: x= 5
*Note: When you multiply or divide a negative number by another negative number, you will automatically get a positive number as the result.
