1. Combine like terms, so add 2.4 to -4.8 to get -2.4
So now you should be left with .02(x+20)-2.4=-9
2. Now eliminate the -2.4 by adding 2.4 to both sides, getting .02(x+20)=-6.6
3. Multiply everything by 50 to make x+20=-333, since 50×.02=1
4. subtract 20 from both sides to get x=-353
the correct answer is 83.
yyyyyeeeeeeaaaahhhhhh bbbbooooiii

Answer:
240
Step-by-step explanation:
If we get 10% off, we still have to pay 100-10 = 90%
Let x be the original price
x *90% = 216
.90x = 216
Divide each side by .90
.90x/.90 = 216/.90
x =240
The original price is 240
