    Didactically, I would say this is too heavy step ahead in comparsion with previous topics.

    Oh thanks, i have now gotten another big of tricks in solving equations.

    By the time you get to 4x - x/3 = 11 that is when you kinda get an idea of what X will be.... But the whole video went into a further detail. But oh well.

    This was confusing as hell. Okay, so there was no information in the course and then you give us this problem and nothing else!

    I think it would have been easier to immediately multiply both sides by 3 to cancel out the fraction. So it becomes: 3(4x - 7) = (x/3 + 4) 3 12x - 21 = x + 12 Add 21 to both sides to get... 12x - 33 = x 12x = x + 33 11x = 33 x = 33 I feel like this video did it the hardest way possible.

    In the steps all it said was "if we ..... both sides of the equation by the same #, both sides will remain equal." And then it throws this at us "4x - 7 = x/3 + 4". You should have explained how to these types of equations in the steps.

    when combining like terms, why did you use '7' why add, why not subtract, why not add 4 to both sides, why no subtract 4? There are more questions than answers here. Then you say we want to subtract x/3 but don't explain why. This video gives me no reference as to the rules of why this is done this way
