Answer:
Ok, so we have the fact that plus +minus=minus
Thats the fact. It always works that way that same signs means positive and different means negative, as explained with logic.
4+(-5)
So we know that 4 is positive and -5 is negative
if you look at it through a number line, substracting 5 from 4 you have
3--->2---->1---->0---->-1
Under zero, the negatives start, so its proved by maths and logic as well.

sorry if im wrong
Answer:
690 and 6,900
Step-by-step explanation:
230
x 33
______
690
+ 6,900
________
7590
First what you wanna do is get y by it’s self. To do that is to first add 5 on each side.
-5+3y=-4
+5 +5
3y= 1
Than you divide 3 on each side and it would give you y=1/3 if it’s a fractions problem but if you looking for decimals you would have to divide 1 by 3 which gets you .33333333.
