Question

What is the solution to the equation below? -3 + sqrt 2x - 1 =8​

Answer 1

Answer:

$x=61$

Step-by-step explanation:

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

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

Add 3 to both sides of the equation:

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

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

Solve the square root:

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

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

$2x-1=121$

$2x-1+1=121+1$ {add 1 to both sides}

$2x=122$

$x=122/2$

$x=61$

hope this helps.......
