Question

What does it mean if an equation is true, false, or open? Give definitions of each.

Answer 1

I'm gonna do the example of this equation 2+2, as we all know when we add it together the sum of it is 4 , here are the examples:                                          2 + 2 = 4 is true 
2 + 3 = 4 is false 
x + 3 = 4 is open
