One can say that
X+7 equals 4Y
but we can not get an answer for X or an answer for Y without knowing one of them first.

The negative of a negative number is a positive number. The reason for this is that the first negative is a place holder for -1. When you have - - 4, that translates into -1 x -4. When you multiply two negative numbers, you get a positive.For example:- - 7 = -1 x -7 = 7- - r = -1 x -r = r
-14 - +7 - -25 = 4
x= Negative 4
(-3) - (-7) = (-3) + (+7) = (-3) + 7 = 4
If: n--3 = -4 Then: n = -7
-7 minus -4 is -3
x = 4 and y = 7
(Positive) 7.
-7--4=-7+4=-3
(-4) - (-7) = (-4) + 7 = 3
Goes towards positive.for instance, -7 minus -7 = 0or -10 minus -4 = -6OR -25 minus -30 = positive 5
Question 3C: Four minus seven equals negative two.
