Question

2x-9(under radical)=1/3

Answer 1

do you mean 2x - 9 = 1/3

Answer 2

\[\sqrt{2x-9}=1/3\]

Answer 3

Ok that makes more sense

Answer 4

Square both sides to eliminate the radical and then solve for \(x\) :)

Answer 5

\(\sqrt{2x-9}= \frac{1}{3}\)
\(2x-9 = \frac{1}{3}^{2}\)

Answer 6

What dont you understand about this question

Answer 7

just making sure i'm doing it correctly.

Answer 8

Ok.

Just square both sides, this will give

2x - 9 = (1/9)
now multiply both sides by 9, this will give

18x - 81 = 1
Add 81 to both sides

18x = 82
x = 82/18
