Answer: X=7/2

Step-by-step explanation:

Answer:

21/6 or 3.5

Step-by-step explanation:

1. Distribute.

2. You should now have 15x-30=9x-9

3. Subtract 9x from both sides to get all of the x's on one side:

(15x-9x)-30=(9x-9x)-9 = 6x-30=-9  

You should end up with 6x-30=-9

4. Add 30 to both sides to get all the constants on one side:

6x+(-30+30)=(-9+30) = 6x = 21

You should now have 6x = 21

5. Divide 6 by both sides to get x alone:

6x/6 = 21/6

FINAL ANSWER:

x = 21/6 (3.5)
