Question

Can you help me with this question ♂️ Solve for x

Answer 1

x = 65

Step-by-step explanation

To solve this equation, first, we have to subtract 3 from both sides,

`\begin{gathered} \sqrt[]{x-1}+3-3=11-3 \\ \sqrt[]{x-1}=8 \end{gathered}`

Next, square both sides of the equation,

`\begin{gathered} (\sqrt[]{x-1})^2=8^2 \\ x-1=64 \end{gathered}`

And finally, add 1 to both sides,

`\begin{gathered} x-1+1=64+1 \\ x=65 \end{gathered}`

Hence, x = 65.
