Answer:
None.
Step-by-step explanation:
6x-20=32
6(8)-20=48-20=28, not 32
--------------------------------------
16-x=12
16-8=8, not 12
--------------------
20-0.4x=13.8
20-0.4(8)=20-3.2=16.8, not 13.8
------------------------------------------------
1x+12=30
x+12=30
8+12=20, not 30
91,000 on each side. 91,000 plus 91,000 equels 182,000
