Given the following equation:


5x+10y=-3

You know, based on the information given in the exercise, that it is a true equation. You can notice that the sum (the result of the Addition) of the terms on the left side of the equation, is:


-3

Then, knowing the above and having the following expression:


5x+10y+7

You can substitute the sum of the equation into the expression:


(5x+10y)+7=-3+7

Finally, adding the numbers, you get that the value of the expression is:


=4
