Hi
x/12 divide by 7xy/4
Recommend comparing the final simplification to the orignal as a final check: |
For example:
I) The final simplification needs to include a 'y' (cannot simply 'erase' it)
II) If one were to somehow get '40' for example in the denominator: highly
unlikely that could even be possible with the presence of the '7' originally.
In a typical 'solve for x'..type problem..so easy to check by simply substituting the value found..
back into the original equation as a means of checking Your answer.
When the instructions are to simplfy an expression, it's a bit more difficult
to 'check your answer', however, many times just 'sight checking' against
the original works well as a means of checking Your work.
