Question

What is the solution of the equation? Helpp!
sqt2x+13 -5=x

Answer 1

\[\sqrt{2x + 13 - 5} = x\]?

Answer 2

Or is it\[\sqrt{2x + 13} - 5 = x\]

Answer 3

The second equation! (:

Answer 4

Okay :)
Start with adding \(5\) to both sides.

Answer 5

can you explain to me what sides?

Answer 6

Add \(5\) to both sides, like this:\[\sqrt{2x +13} - 5 + 5 = x + 5\]

Answer 7

ok

Answer 8

So, what do you have now?

Answer 9

\[\sqrt{2x+13}=x+5\]

Answer 10

now square both sides :-)

Answer 11

\[\sqrt{13}=5\]

Answer 12

@kudrick16

Lets see this question :)


\[\sqrt{2x+13}=x+5\]

Squaring both sides

Answer 13

\[(\sqrt{2x+13})^2=(x+5)^2\]

Hint :
Use (a+b)^2 formula.

Answer 14

@kudrick16
Please solve...

Answer 15

\[\sqrt{169}=25\]

Answer 16

25x*

Answer 17

@kudrick16


(a+b)^2=a^2+2ab+b^2


(x+5)^2=


\[\sqrt{2x+13}=(2x+13)^{1/2}\]

Answer 18

@kudrick16

I think you need to work on your basics first ...

Answer 19

Now i don't know have a clue what too do from here on out

Answer 20
