Answer:
-21
Step-by-step explanation:
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
