+343 This means x - y= The difference so
\(x - (-9) = -74 <=> x= -74 - 9 = -83 \)
so the number is \(-83\)
Hope this helps!

+1443 i think you have to add to move the -9 over. so 9 plus -74. am i right? im confused.
+343 No its :
\(x - (-9) = -74 <=>x +9 = -74 \) we remove from both parts the 9 so \(x +9 -9 = -74 - 9 <=> x=-83\)
Now you understand it?
