-3-2w-2=8
To find the opposite of 2w+2, find the opposite of each term.
-5-2w=8
Subtract 2 from -3 to get -5.
-2w=8+5
Add 5 to both sides.
-2w=13
Add 8 and 5 to get 13.
w=\frac{13}{-2}
Divide both sides by -2.
w=-\frac{13}{2}
Fraction \frac{13}{-2} can be rewritten as -\frac{13}{2} by extracting the negative sign.
