8xーX<0

To solve the inequality \( 8x - x < 0 \), we can simplify it first:

1. Combine like terms: \[ 7x < 0 \]

2. Next, divide both sides by 7: \[ x < 0 \]

So, the solution to the inequality is: \[ x < 0 \]

This means that any value of \( x \) that is less than 0 satisfies the given inequality.
