## anonymous one year ago Which statement is true for the equation 3x − 3x − 2 = −2?

1. anonymous

where are the statements?

2. anonymous

It has no solution. It has one solution. It has two solutions. It has infinitely many solutions.

3. anonymous

hello.........

4. Nnesha

try to solve it first if you get equal sides then infinitely many solution example 4=4 if both sides are not equal then no solution like 9=7

5. Nnesha

if you get x = something then one solution

6. Nnesha

$\huge\rm \color{blue}{3x − 3x }\color{reD}{− 2 = −2}$combine like terms

7. DecentNabeel

3x − 3x − 2 = −2 no solution add 2 on both sides 3x-3x=-2+2 0=0

8. Nnesha

nice try ...

9. Nnesha

but guess what

10. anonymous

what

11. Nnesha

12. anonymous

no solution

13. Nnesha

alright then.

14. anonymous

is it right

15. Nnesha

I believe you didn't read my first comment

16. anonymous

wdy mean

17. anonymous

@sweetburger can you check this out

18. Nnesha

$$\color{blue}{\text{Originally Posted by}}$$ @Nnesha if you get equal sides then infinitely many solution example 4=4 if both sides are not equal then no solution like 9=7 $$\color{blue}{\text{End of Quote}}$$

19. Nnesha

3x-3x = ?

20. anonymous

0

21. Nnesha

so you get equal sides $\huge\rm \color{blue}{\cancel{3x − 3x} }\color{reD}{− 2 = −2}$ -2=-2 so answer is ?

22. anonymous

o

23. Nnesha

what's that ?

24. Nnesha

$$\color{blue}{\text{Originally Posted by}}$$ @Nnesha if you get equal sides then infinitely many solution example 4=4 if both sides are not equal then no solution like 9=7 $$\color{blue}{\text{End of Quote}}$$ you got -2=-2 so which one is correct answer?

25. anonymous

one solution

26. DecentNabeel

so @Nnesha what is the value of x.. you say many solution

27. anonymous

i am confused

28. Nnesha

if you get equal sides then infinitely many solutions if both sides are not equal then no solution

29. Nnesha

you got -2=-2 both sides are equal so answer is ?

30. DecentNabeel

only tell me what is the value of x..

31. anonymous

so there is one solution

32. Nnesha

no

33. anonymous

it is zero

34. Nnesha

x cancels out right you get -2=-2 equal sides

35. Nnesha

let me repeat t if both sides are equal like 4=4 then your answer would be infinitely many solutions

36. DecentNabeel

@Nnesha you mean no value of x.. you said previous comment in many solution.. so what solution

37. anonymous

oh

38. Nnesha

4=9 no solution x= something , one solution 4=4 infinitely many solution

39. Nnesha

so what do you think ?

40. anonymous

many solutions

41. Nnesha

thats right!

42. anonymous

thank you

43. Nnesha

Yw

44. DecentNabeel

no the answer is.. no solution

45. Nnesha

how is it no solution ?

46. DecentNabeel

3x-3x=0 so that the variable is the cancle out

47. Nnesha

okay you will get 0=0 so thats mean both sides are equal

48. anonymous

soooo

49. Nnesha

so what ?

50. DecentNabeel

then solve it.. so what is the variable for solving.. there is no variable for sloving.. so there is no solution

51. Nnesha

......

52. Nnesha

repeating when you get equal sides 't the end then infinitely many solution believe it or NOT

53. DecentNabeel

not

54. Nnesha

as you wish, sir

55. DecentNabeel

AS you wsih @Nnesha expert

56. Nnesha

you can tag some expert here i wouldn't mind ..

57. DecentNabeel

yes i have no mind.. i clear the concept

58. DecentNabeel

This solution could also be stated as "all real numbers" or "all reals" or "the whole number line"; expect some variation in lingo from one text to the next. Note that, if I had solved the equation by subtracting a 5 from either side of 5 + 4x = 5 + 4x to get "4x = 4x", I would have ended up with nothing other than another trivially-true statement. I could also have subtracted both 4x and 5 from both sides to get "0 = 0", but the solution would still be the same: "all x". Don't be surprised if, for "all real numbers" or "no solution" equations, you don't necessarily have the exact same steps as some of your fellow students. Since there are infinitely-many always-true equations (like "0 = 0") and infinitely-many nonsensical equations (like "3 = 4"), there will be many ways of arriving at these answers

59. Nnesha

you can substitute x by any number you will get equal sides $\huge\rm 3(9)-3(9)-2=-2$ or let plug in 2 $\huge\rm 3(-2)-3(-2)-2=-2$ both sides are e qual how can you say that there is no solution ?

60. DecentNabeel

i think both are true.. some expert say no solution.. and some one is many

61. Nnesha

well you can plug in any number you will get equal sides so thats means infinitely many solution

62. DecentNabeel

http://www.purplemath.com/modules/solvelin4.htm @Nnesha expert you can see it

63. Nnesha

so http://prntscr.com/7yn3yb solution is all x thats mean any number can be x

64. Nnesha
65. DecentNabeel

so the finally answer is.. this is no solution for this equation.. but many solution for all x

66. DecentNabeel

@Nnesha are you clear

67. Nnesha

wait what ?

68. Nnesha

x can be any number so infinitely many solution :=)

69. DecentNabeel

yes i agree many solution for x.. but there is no solution for equation

70. Nnesha

what do you mean ? i already posted some example where we get equal sides so thats mean there are many solution for equation

71. DecentNabeel

ohhhhhhhhhhhhhhhh

72. DecentNabeel

as you wish

73. Nnesha

as you wish ? no thats how it works *mathematically*
