Question

Find the value of 3u+3 given that -11u-9=2.
Simplify your answer as much as possible.

Answer 1

Answer:

  0

Step-by-step explanation:

Solving the given equation for u, we have ...

  -11u = 11 . . . . add 9

  u = -1 . . . . . . divide by -11

Then the value of 3u+3 is ...

  3(-1) +3 = -3+3 = 0

3u +3 = 0

Answer 2

Answer:

-11u-9=2

-11u=2+9

-11u=11

then u divide 11 on both sides

u=0

Where ever u see u place 0

3u+3

3(0)+3

0+3
