Answer:
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
Answer:
-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
