So 2x+12=5x-9
you want all of the unknowns on one side and all of the known values on the other or
subtract 2x from both sides
12=3x-9
add 9 to both sides
21=3x
divide both sides by 3
7=x
All real numbers greater than or equal to -3
Answer:
-0.5,-2/5,0,0.67,7/9
Step-by-step explanation:
Well since the bigger the negative the lesser the number it is itself so -0.5 is the least. The fraction -2/5 turn It into a decimal and you’ll get -0.4 which is greater then -0.5. Then the next number is 0 which is greater then any negative number. Then its 0.67 becuase the other positive fraction Is 0.78 simplified.
