How many solutions can be found for the equation 4x - 8 - 4x = 9? (4 points)

Ksivusya [100]

Answer:

A. Zero

Step-by-step explanation:

This would have no solution because when you try to solve the equation and simplify, the 4x's cancel out, leaving no variable and making the equation reduce to: -8=9 which is false, and therefore, this has no solution.

I hope this helps!
