So, what I got was actually -9/-3

  • Liv1234
Do you want me to show you how I got it?

\[-4*2-1=-9 1+2=3\]

That is supposed to say -9 and 1+2

@ganeshie8 is that correct? or did I miss a step?

First, start out by plugging in what H equals.. \[\frac{ -(4*2-1) }{ 1+2 }\] Then evalute "1+2" giving you.. \[\frac{ -(4*2-1) }{ 3 }\] Then multiply "-4*2".. \[\frac{ (-8-1) }{ 3 }\] Subtract -8-1... This gives you the final answer of.. \[- \frac{ 7 }{ 3 }\]

But -8-1 is -9..

  • Liv1234
Can someone help me? How can it be -7/3 if -8-1 is -9?
