OpenStudy (sleepyjess):

Can you show me how you got 9 for the first one?

OpenStudy (phi):

you could check your answers by replacing x with your answer and seeing if you get the "right side" number

OpenStudy (anonymous):

I'm kinda in a hurry.. did I get any correct?

OpenStudy (phi):

for example for Q1: replace x with 9 4*9 (4 times 9) is what ?

OpenStudy (sleepyjess):

Beware of answers provided with no proof or back-up information.

OpenStudy (sleepyjess):

I offered to go through them step by step. That offer still stands if you would like to use it.

OpenStudy (radar):

An example is your number 2. Try that answer that you have chosen. 5x - 15 = 50 5(7) - 15 = 50 35 - 15 = 50 20 = 50 Now does that really ring of the truth???? !!!
