Solve for x using the addition principle: -8+x= -24 would that be -8x=-24 which equals 3?

    you add 8 to each side of the equation -8 + x + 8 = -24 + 8

    what happens to the lefthand side? - what does it simplify to?

    no - 8 + 8 = 8 - 8 = 0

    the temperature is -8 degrees then it rises 8 degrees to give 0 degrees 8 degrees is 'added'

    do you see how the diagram relates to -8 + 8 = 0 ?

    the reason I added 8 to left side was so we would only have x left -8 + 8 + x = 0 + x = x

    yes I understand when you do it, but get frustrated when I try to do it my self.

    practice simple examples and you'll gain confidence remamber to do the same operation ( + 8) to both sides of the equation an equation is like a balance

    OK now we have x left so then it would be X=-24+8 I will ty.

    so we still add 24+8 right?

    no we add 8 to minus 24 (-24) check out the thermometer

    if we add 1 to -24 that is go up 1 degrree it gets to -23 right?

    and add 1 more dgree we get -22 right so what do we get to if we 8 to -24?

    if I look at your nice graft thats what I come up with.

    right -16 is correct so we get x = -16 - though i dont think my graph is all that nice!! lol

    so do I have to figure what x is yet or is that simplified enough?

    no thats it x = -16 in algebra you need to get used to negative values and how to manipulate them

    the solution to the equation is x = -16

    I will for sure use your graft, because it makes sense to me.

    ok remember that everything below the x ( horizontal axis) is negative also everything to left of the y-axis is negative |dw:1359326605166:dw|
