A situation equation follows the order of the story problem.
For instance:
Johnny has 8 apples, he eats some, and has 3 left.
The situation equation would be: 8 - a = 3
A solution equation is the equation that would help you find the solution. Your brain doesn't automatically know what "a" is, it has to rearrange the order of the equation and then solve.
The solution equation would be: 8 - 3 = a, then you would solve it.

What is the difference between an equation and an expression?
Expression has no answer. a equation has an answer
What is the difference between no solution and undefined?
undefined means you can not do the operation (5/0 is undefined) no solution refers to an equation not having an answer. a solution is a number which you can plug into the variable of an equation and get a true statement. So having no solution means there is no number which you can plug in and get a true statement. As a fraction is not an equation, but an expression it is not right to say that 5/0 has no solution. There is no variable in 5/0, nothing to plug into to get a true or false statement.
What is the difference between quadratic equation and quadratic expression?
an equation has an equals sign.
What is the difference between a number sentence and a number model?
A number sentence has a letter as its solution while a number model has the solution. I remember this by thinking of a number model as a model of what the full equation should be and a number sentence being the opposite of that.
