u = - 2/3
Step-by-step explanation:
-3 = - 1 / (u+1)
Multiply each side by (u+1)
-3 * (u+1) = - 1 / (u+1) * (u+1)
-3 (u+1) = - 1
Distribute
-3u - 3 = - 1
Add 3 to each side
-3u - 3+3 = - 1+3
-3u = 2
Divide each side by - 3
-3u/-3 = 2/-3
u = - 2/3

-2/3
Step-by-step explanation:
multiply each side by u + 1 to get it out of the denominator
-3 (u + 1) = - 1
now use distributive property
-3u - 3 = - 1
add the 3 to move it over
-3u = 2
now divide by - 3
u = - 2/3
