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)
