-2\left(8-4-\left(-w\right)\right)-8=4\left(w+5\right)
To find the opposite of 4-w, find the opposite of each term.
-2\left(8-4+w\right)-8=4\left(w+5\right)
The opposite of -w is w.
-2\left(4+w\right)-8=4\left(w+5\right)
Subtract 4 from 8 to get 4.
-8-2w-8=4\left(w+5\right)
Use the distributive property to multiply -2 by 4+w.
-16-2w=4\left(w+5\right)
Subtract 8 from -8 to get -16.
-16-2w=4w+20
Use the distributive property to multiply 4 by w+5.
-16-2w-4w=20
Subtract 4w from both sides.
-16-6w=20
Combine -2w and -4w to get -6w.
-6w=20+16
Add 16 to both sides.
-6w=36
Add 20 and 16 to get 36.
w=\frac{36}{-6}
Divide both sides by -6.
w=-6
Divide 36 by -6 to get -6.
