$\sqrt{1 + \frac{x}{ 9} } = \frac{13}{?3}$
​

Answer 1

Step-by-step explanation:

$\sqrt{1 + \frac{x}{ 9} } = \frac{13}{?3} </p><p>$

$square \: on \: both \: side$

$1 + \frac{x}{9} = \frac{169}{9}$

$x = 169 - 9$

$x = 160$

$\frac{9 + x}{9} = \frac{169}{9}$

9+ x= 169

x=160

Answer 2

Step-by-step explanation:

\sqrt{1 + \frac{x}{ 9} } = \frac{13}{?3}1+9x=?313

square \: on \: both \: sidesquareonbothside

1 + \frac{x}{9} = \frac{169}{9}1+9x=9169

x = 169 - 9x=169−9

x = 160x=160

\frac{9 + x}{9} = \frac{169}{9}99+x=9169

9+ x= 169

x=160
