-4 - 1 = -4 + (-1) = -5
(-3)-(4)=(-3)+4=1 Minus times minus equals plus. The reason for this we need not discuss.

-4 - (-3) = -4 + 3 = -1 When there are two negatives the answer is positive =7
It equals positive seven.
-3 - (-1)= -3 + 1= -2-2
(-3)-(4)=(-3)+4=1 Minus times minus equals plus. The reason for this we need not discuss.
x = 4 and y = 7
5
x= Negative 4
x = 4 and y = 7 which will satisfy both equations
-4 - (-3) = -4 + 3 = -1 When there are two negatives the answer is positive =7
It equals positive seven.

4.
-1 -2 multiplied by another -2 equals 4 .4-5=-1
Negative 20 minus negative 4 is calculated by adding the two numbers together, since subtracting a negative is the same as adding. Therefore, it becomes -20 + 4, which equals -16. So, negative 20 minus negative 4 is -16.
If: n--3 = -4 Then: n = -7
