Question

Which steps below show an equation that has NO solution?



5(x - 3) + 2 = -x + 47

5x - 15 + 2 = -x + 47

5x - 13 = -x + 47

5x = -x + 60

6x = 60

x = 10


6x - (6 + 4x) = 26

6x - 6 - 4x = 26

2x - 6 = 26

2x = 32

x = 16


3x + 9x - 5 = 2(6x + 1) - 7

3x + 9x - 5 = 12x + 2 - 7

12x - 5 = 12x - 5

-5 = -5


-4(1 - 6x) = 24x - 22

-4 + 24x = 24x - 22

24x = 24x -18

0 = 18
PLEASE I NEED HELP ON HOMEWORK

Answer 1

just for the last one. 0=18 ?? make sense??

Answer 2

no its a full equation

Answer 3

-4(1 - 6x) = 24x - 22

-4 + 24x = 24x - 22

24x = 24x -18

0 = 18

Answer 4

i guess you are supposed to say the last step, where you get \(0=18\)

Answer 5

oh okay thanks both of you :)

Answer 6

btw i am not sure that is right
i mean i am sure the equation has no solution, and i am sure you know it when you get \(0=18\) but the question is written in such a weird way, it is not clear what it wants
either: the last step
or: the whole thing

Answer 7

okay :) thanks for answering :)
