x = -8
Step-by-step explanation:
Step 1: Subtract 1 from both sides
[tex]1 - 10x - 1 = 81 - 1 \\ - 10x = 80[/tex]
Divide both sides of the equation by -10
[tex] \frac{ - 10x}{ - 10} = \frac{80}{ - 10} \\ \\ x = - 8[/tex]
Answer:
-8
1. Subtract 1 from each side of the equation ---> -10x = 80
2. Divide each side of the equation by -10 ----> x= -8
Then you get your answer of -8
