+233 Which property are you using when you solve 5x is > or = 30 by dividing each side by 5?
I was sick and absent when we went over this in class. I would appreciate if you could explain how to get the answer.
Many thanks.
+118672 Why does it have to be a property?
\(5x\ge30\)
You are dividing the left hand side by 5 because you want to get the x by itself.
and
you are dividing the rhs by 5 becasue the equation must stay balanced.
Think of an equation like a see saw or tetter totter or balance scale.
If it is balanced that is the 2 sides are equal then if you change one side then you must change the other side in the same way if you want it to remain balanced.
