Solving Equations (one, many or no solutions)

What is the definition of one solution?

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

• no matter what number is substituted in for the variable, the equation will NEVER be true

• there is only ONE number you can plug in for the variable to make the equation true
