Answer:
Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division.
Step-by-step explanation:
The difference is 
.
Step-by-step explanation:
Step 1:
The polynomial 
is subtracted from the polynomial 
.
If we write this as an equation, we get
.
To subtract the polynomials, we group up the terms based on their variables.
In this subtraction, there are two variables i.e. 
and 
and there is one constant term.
Step 2:
The subtraction of the variables; 
.
The subtraction of the variables; 
.
The subtraction of the constants; 
.
So 
.
