This is the same problem as before. Just different numbers.

4. chevygirl

Well if you knew me good enough you would now that I don't learn real easy. It isn't that I am choosing not to learn I just don't get how to do it.

Multiply both sides by 7.

7. chevygirl

-35 and -7?

8. skullpatrol

|dw:1356563975056:dw|

9. chevygirl

Am I right?

10. skullpatrol

11. chevygirl

-30 and -2?

12. skullpatrol

|dw:1356564176650:dw|

13. phi

no, when you multiply 7 times (z-5)/7 $\frac{7}{1}\cdot \frac{(z-5)}{7}$ you get $\frac{7(z-5)}{7}$ or $\frac{7}{7}\cdot \frac{(z-5)}{1}$ 7/7 is 1 and (z-5)/1 is (z-5) multiplying by the 7 makes the denominator "go away"

14. chevygirl

OK????

15. phi

see skull's first post

16. chevygirl

17. phi

you do not get -35 and -7? you get z-5= -7

18. chevygirl

ok. but never mind

19. skullpatrol

The answer is {-2} because -2 is the only number that will make z = -2 a true statement.

20. skullpatrol

-2 = -2

21. chevygirl

ok but the only reason I am asking these questions is because I dont get how to do them @Harkirat

22. Harkirat

@chevygirl Well ask your teacher to explain,in detail, how to solve such sums....u cannot go through life asking others to solve them for you......being able to do themselves will boost your confidence...

23. chevygirl

well if my teachers were here i would ask them but they arent here so I cant AND i got put in a different class because i got behind because i am not good at math

24. skullpatrol

25. chevygirl

ok. i will try to REMEMBER this

26. skullpatrol

Would you like me to explain how I solved the original equation?

27. chevygirl

um no thanks cause i have to do another test

28. skullpatrol

Is it a math test?

29. chevygirl

yeah

30. skullpatrol

If I explain this one you can use the method on most of your other questions.

31. chevygirl

yeah but i dont know if it is these type of questions or not

32. skullpatrol

There are a lot of these types of questions in math.

33. skullpatrol

34. chevygirl

7

35. skullpatrol

Do you know what an inverse operation is?

36. chevygirl

yeah

37. skullpatrol

inverse operations: Operations that "undo" each other for example multiplication and division.

38. skullpatrol

If the side containing the variable involves a certain order of operations, apply the inverse operations in the opposite order.
