I really need help understanding how to do things like 20-4x-9.50
Please help.
Thanks.
+505 When you do equations like this, reorganize the numbers because you are subtracting. Reorganise them like this: 20-9.50-4x.
It only works with equations like this: 20-17-2 or 19-6x-4-3 because of the communitive properties. Btw, it factors out like this: 11.50-4x.
