    My answer is: 8x-x=21 8.3-3=21 24-3=21 x=21 The answer is 3, But why the video explanation is harder to understand.. The video says 8x minus 1. Where did he get the 1. hmmm

    its very confusing when he uses a . to represent multiplication. for example 4 multiplied by 6 he would write as 4 . 6, which i find very confusing. 4 x 6 or 4(6) is much more clear.

    why don't you show the specific steps into how you will breakdown 7X=21 which gives X=3. A beginner will absolutely not understand. Please add the specific steps.

    I Think this topic was quite rushed. I didn't understand the beginning as it was skimmed over, so I did not understand the rest.

    On the previous page it actually said 8 . x - x = 21. He wrote 8x -x = 21. There is no way anyone is going to get that right unless you watch the video to see that it was a typo. Someone needs to fix that.
