Question

Is the following always, sometimes, or never true?

14 + 3x – 7 = 7x + 7 – 4x

A, Always
B. sometimes
C. never

Answer 1

Try to move all the numbers that has an x involved to one side and everything else to the other side of the equality sign. Then simplify... If you get a true statement, then the answer is A. If the get a false statement, then the answer is C.

A true statement can be the following (an example):
x = x
or 1 = 1

Answer 2

okay im going to do that now

Answer 3

wait do i add all of the numebers with the x's in them to one side?

Answer 4

well... you move them first, along their x's.
For example if you have 2x + 3 = 5x, then you would subtract both sides by 2x such that you have the following:

3 = 5x - 2x

Now you tell me if we are adding the 5 to the 2 or are we subtracting?

Answer 5

3=3
