Question

Which statement is true about the meaning of the equation

Answer 1

An equation says that two things are equal. It will have an equals sign (assuming you know what that is)  like this:
7+2=10-1
What the equal says on the left, is equal to the answer on the right. 
Basically, it's a statement saying "equals that"

I don't fully understand your question, but I hope it helped you at least a little.
