Question

.Which of the following equations has no real solutions?
A. 9x - 3 = 9x - 3
B. 9(x - 3) = 9x - 27
C. 9x - 3 = 27x - 3
D. 9(x + 3) = 9(x + 11)

Answer 1

@armyengineer225 can u help me on this one?

Answer 2

First simplify each equations\

Answer 3

@nelsonjedi can u explain how to do that? sorry...

Answer 4

Let's do this one in steps: A) Subtract 9x from both sides, and you would have 0-3 = 0-3. Add 3 to both sides, and it is 0 = 6.
B) Divide by 9, and you have x-3 = x-3. Again, 0 = 6.
C) Subtract 9x from both sides, and you have -3 = 16x -3. 16x = -6, so x = -6/16. This one has a solution.
D) Divide by 9, and x+3 = x+11. x = x+8, 0 = 8... Are you supposed to choose only one answer?

Answer 5

yes isnt there two that i could choose?

Answer 6

It appears that there should be 3 you can choose, A, B, and D, since a singular number cannot equal 6. Perhaps the question is, which one does have a solution? In which case, the answer would be C.

Answer 7

I'm sorry, I meant a singular number cannot equal 0.

Answer 8

Answer 9

i dont know why it says that... there is a possibility it could of been a typo

Answer 10

i went ahead and chose c it was wrong

Answer 11

Perhaps, though I may be wrong. You may want to talk to your teacher.

Answer 12

Ah I see, so they multiplied everything out.

Answer 13

oh... okay

Answer 14

Distribute to simplify and what do you have

Answer 15

well can anybody help me with this? @armyengineer225 @luckyted @nelsonjedi

Answer 16

solution to these equations:
A) for every x in R, 9x - 3 = 9x -3, left side is exactly equals to right
B) just like A.
C) simplify to 9x=27x, so x = 0.
D) no solution for x, such that 9x-27 = 9x-99.

so the answer is D.

Answer 17

oh that makes sense thank you so much @luckyted

Answer 18

but i still need help with the last question i asked

Answer 19

(x/5)+2 = 4. Subtract 2 from 4, you have (x/5) = 2. Multiply by 5 to clear the fraction, you have x = 10.

Answer 20

thank you! @armyengineer225

Answer 21

No problem. Sorry about the first question!

Answer 22

it ok! :)
