3(3u-2)=2(3u+3)
What is the steps

Hopes this helps:

u = 4

1. Expand.
9u - 6 = 6u + 6

2. Add 6 to both sides.
9u = 6u + 6 + 6

3. Simplify 6u + 6 + 6 to 6u + 12.
9u = 6u + 12

4. Subtract 6u from both sides.
9u - 6u = 12

5. Simplify 9u - 6u to 3u.
3u = 12

6. Divide both sides by 3.
u = 12/3

7. Simplify 12/3 to 4.
u = 4

Okay so yes for the first one it is 4 Sig digs

And I believe you are correct on the 2nd one.. I beleive it is also D.

Go with your gut! And good luck! :D
