Question 23708: PLEASE HELP ME SOLVE THIS!
36-d=17
thank you for your time
Answer by longjonsilver(2297)   (Show Source):
You can put this solution on YOUR website! 36-d=17. This time a different approach, so you can see a diiferent method:
subtract 36 from both sides, to give -d = -19
Now, this says -1d equals -19. But we want to know what 1d is equal to, not -1d. So we need to manipulate the -1 (NOT THE d)...the d has to remain.
We do this by dividing by -1, since -1/-1 is 1... anything divided by itself is 1.
So, divide both sides by -1, to give d = -19/-1
--> d = 19
=============================================================
Doing it the way i did the first one, we would have:
36-d=17
Add d to both sides: 36 = 17 + d --> or 17+d = 36
subtract 17 from both sides, to give, d = 19
OK?
