Ok, so when you are solving an equation, and you have an answer such as
5x=0 , does that mean that it is no solution or all real #s?
And, when the answer is
4=4 , does that mean it is no solution or all real #s?
And when the answer is
2x=2x, does that mean it is no solution or all real #s?
Thank you
