Question

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

Answer 1

`x=61`

Explanation:

`-3+√(2x-1) =8`

`√(2x-1) -3=8`

Add 3 to both sides of the equation:

`√(2x-1)-3+3=8+3`

`√(2x-1)=11`

Solve the square root:

`√(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.......
