7+(-9)+6+(-10)+(-13)+(-5)=
7-9+6-10-13-5=
-24
mean is the sum of all the numbers divided by the total number of numbers within the data.
-24÷6=-4
The mean is -4.
If you're trying to solve for y
-2y = 8
Divide -2 to both sides

Cancel out the -2 on the left, Divide the -2 to the 8 on the right so
y = -4
-8+4x=-20x-25+7x
4x+20x-7x=-25+8
17x=-17 /17
x=-1
