Find a value of the variable that shows that the two expressions are not equivalent. Answers may vary.
anonymous
  • anonymous
Put a = 1
anonymous
  • anonymous
so then it would make the problem 8/7
anonymous
  • anonymous
The first one becomes 8/7 and the second 1 Put a = 2 and u get 9/7 and 2
anonymous
  • anonymous
how would i show my work for that?
anonymous
  • anonymous
???????
anonymous
  • anonymous
First expression is a+7 ---- 7 Putting a=1, we get 1+ 7 ie 8/7 ----------- (A) ---- 7 The second expression is a Putting a= 1 , we get a = 1 --------------(B) From (A) and (B) we can see that the first expression is not equal to the second.

  • anonymous
Similarly by replacing a by 2 in the two expressions you will get 9/7 ---- (A) and 2 ------ (B) Hope it is clear now??
anonymous
  • anonymous
so the answer is 1?
anonymous
  • anonymous
See, you have to show that the two expressions are not equivalent, that is values of a + 7 and a are not equal/equivalent ----- 7
anonymous
  • anonymous
So from (A) u hv a + 7 8 ----- = --- 7 7 and From (B) a = 1 So their values are not equivalent
anonymous
  • anonymous
Is it clear now???
anonymous
  • anonymous
....mmmm ok
anonymous
  • anonymous
sorry im really stupid when it comes to math....
anonymous
  • anonymous
Pls don't use the term stupid NOBODY in this world is stupid Its only that some people r lucky to get teachers who explain concepts nicely and clearly The unlucky ones do not get good teachers and hence their concepts r not clear
anonymous
  • anonymous
and it doesnt help that its an online class...:( oh well...im still learning...
anonymous
  • anonymous
Well even online classes can be good I teach a kid in America online and make sure he gets the concepts
anonymous
  • anonymous
We do more examples if required
anonymous
  • anonymous
