-1+x-x=x-8+(-x)

You solved it EXACTLY correctly, Rosala....there is NO solution when we end up with an "absurd" answer!!!

Notice in the original problem that the x's cancel out leaving us with -1 = -8....that's not possible!!!

So Jocelyn we shall solve this like

-1+x-x=x-8+(-x)

( first step would be subtracting the x's in the first expression which gives a zero so we wouldnt write it)

-1=x-8+(-x)

(now we will take our -8 to the other side and change it to 8 as when bringing a variable or a number to other side we change its sign)

-1+8=x+(-x)

( now we will subtract them both and see what we get)

7=0

so sorry this question isnt correct or i dont know , maybe i didnt solve it properly but i checked in the calculator on the hme page and it doesnt give a proper answer so i guess theres a problem in the question!

oh yeah!i just completely didnt notice it!thank you!
