Answer:

$x=61$

Step-by-step explanation:

$-3+\sqrt{2x-1} =8$

$\sqrt{2x-1} -3=8$

<u><em>Add 3 to both sides of the equation:</em></u>

$\sqrt{2x-1}-3+3=8+3$

$\sqrt{2x-1}=11$

<u><em>Solve the square root:</em></u>

$\sqrt{2x-1}=11$

$2x-1=11^{2}$

$2x-1=121$

$2x-1+1=121+1$ <em> {add 1 to both sides}</em>

$2x=122$

$x=122/2$

$x=61$

<u><em>hope this helps.......</em></u>
