-4u-4=2\left(1-2u\right)-6
Use the distributive property to multiply -4 by u+1.
-4u-4=2-4u-6
Use the distributive property to multiply 2 by 1-2u.
-4u-4=-4-4u
Subtract 6 from 2 to get -4.
-4u-4+4u=-4
Add 4u to both sides.
-4=-4
Combine -4u and 4u to get 0.
\text{true}
Compare -4 and -4.
u\in \mathrm{R}
This is true for any u.
