## rejectz48 2 years ago 3 + 6z = 13 + 6z What does z equal?

• This Question is Open
1. Albertoimus

3+6z=13+6z 6z=13+6z-3 6z=10+6z z=(10+6z)/z

2. rejectz48

thank you @Albertoimus

3. Albertoimus

oops sorry, the last one should be z=(10+6z)/6 . sorry, other than that you should be good.

4. TuringTest

subtract 6z from both sides

5. rejectz48

no problem @Albertoimus thanks any way

6. rejectz48

7. TuringTest

and what did you get? the answer provided by Albertoimus is wrong btw

8. rejectz48

z=-10

9. TuringTest

no that is incorrect 3 + 6z = 13 + 6z - 6z - 6z what are you left with?

10. Albertoimus

why would you subtract -6z? s/he'll end up with 3=13, which is incorrect. s/he's trying to solve for z.

11. rejectz48

3=13+1z @TuringTest

12. TuringTest

@rejectz48 no, what albertoinus has is the correct result of subtracting 6z from both sides @Albertoimus this does tell you the answer; namely that there is no answer that is, no real solutions since 3=13 is never true.

13. rejectz48

so there is no solution @TuringTest

14. Albertoimus

the solution should be z=(10+6z)/6. however, if you don't have a number to replace z, then there's no solution.

15. TuringTest

if you follow through what you have and try to isolate z you get z=(10+6z)/6 z=5/3+z 0=5/3 again you see that by trying to solve for z you get a contradiction

16. rejectz48

ok.... @TuringTest @Albertoimus

17. Albertoimus

all in all, no solution.

18. ChmE

Possible solutions... x is unknown, a and b are constants x=a, one solution (a) x=x or a=a, infinite solutions a=b, no solutions
