3u+6+u=4\left(u-1\right)+10
Use the distributive property to multiply 3 by u+2.
4u+6=4\left(u-1\right)+10
Combine 3u and u to get 4u.
4u+6=4u-4+10
Use the distributive property to multiply 4 by u-1.
4u+6=4u+6
Add -4 and 10 to get 6.
4u+6-4u=6
Subtract 4u from both sides.
6=6
Combine 4u and -4u to get 0.
\text{true}
Compare 6 and 6.
u\in \mathrm{R}
This is true for any u.
