Question

3 + 6z = 13 + 6z What does z equal?

Answer 1

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

Answer 2

thank you @Albertoimus

Answer 3

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

Answer 4

subtract 6z from both sides

Answer 5

no problem @Albertoimus thanks any way

Answer 6

i already did that @TuringTest

Answer 7

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

Answer 8

z=-10

Answer 9

no that is incorrect
3 + 6z = 13 + 6z
- 6z - 6z

what are you left with?

Answer 10

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

Answer 11

3=13+1z @TuringTest

Answer 12

@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.

Answer 13

so there is no solution @TuringTest

Answer 14

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

Answer 15

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

Answer 16

ok.... @TuringTest @Albertoimus

Answer 17

all in all, no solution.

Answer 18

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
