What is the definition of no solution?

• no matter what constant is substituted in for the variable, the equation is ALWAYS true

• no matter what constant is substituted in for the variable, the equation will NEVER be true it is a FALSE STATEMENT

• only this ONE solution will make the equation true

• no matter what constant is substituted in for the variable, the equation is Sometimes true
