What is the justification for each step in the solution of the equation?
54+2x=5x−3(2+6x)
select from the drop-down menus to correctly justify each step.
−5(4x+6)< −18x+6+4x
- given (example)
−20x−30< −18x+6+4x
combine like terms - distrubutive property - subtraction property of inequality
−20x−30< −14x+6
- addition property of inequality - combine like terms - subtraction property of inequality
−6x−30< 6
- addition property of inequality - division property of inequality - multiplication property of inequality
-6x< 36
- addition property of inequality - multiplication property of inequality - division property of inequality
x> -6
- subtraction property of inequality - division property of inequality - addition property of inequality
