"If 5x+7=-13, then x=-4"
The contrapositive is the inverse and converse of a conditional statement. So, the contrapositive of this statement would be:
"If x does not equal -4, then 5x+7 does not equal -13."
I don't quite understand the ten strategy, or what EXACTLY you're asking. But, what you can do is when you add a one digit number plus a nine, just change the nine to a ten and subtract one. It is very easy. So, 7+10 equals 17, subtract one and you get 16 which is 7+9. It is always one less than anything plus 10.
