well, if you want to add apples to bananas you can't do that
it's the same with variables, the coefficients can be different but to add and subtract the variables have to be the same for ex:
you can't do 4x+3y because they have different variables
you can do 4x+3x because they have the same variables all you do is add the coefficients and keep the variable so you would get 7x
True.
Yes.
Addition and subtraction are reverse operations.
Addition is the inverse operation to subtraction.
Subtraction can be seen as the inverse operation to addition.
that we can use it
it is the number you would use to solve the problem
True.
You don't. You use the GCF to reduce the answer once the addition or subtraction is complete.
Yes.
Solving • Work backward to isolate the variable and solve the equation.Multi-Step • Use subtraction to undo addition, and use addition to undo subtraction.Equations • Use multiplication to undo division, and use division to undo multiplication.
