Answer 1

\[\sqrt{8x + 5} = 3\sqrt{x}\]

Answer 2

square both sides to rid of the square roots

Answer 3

So it would be:
64x + 25 = 9 + x^2?

Answer 4

no 8x + 5 has a square root over it so think of it like a force field and you can only rid of it with a square thus depleting both, but doing no harm to the 8x + 5

Answer 5

same with the X on the other side

Answer 6

So it would be 8x + 5 = 9x?

Answer 7

yup, then combine likes terms and presto

Answer 8

Thanks! Do you think you could help me with one more? Not sure whatg to do with thesee, why do they have the lines in front of them?:
\[|x+2| = 3\]
