Question

Hi can you help me find the correct answer to this problem?

Answer 1

we have the equation

`\begin{gathered} √(10x-1)=7 \\ \end{gathered}`

Solve for x

Step 1

squared both sides

`\begin{gathered} 10x-1=7^2 \\ 10x-1=49 \\ 10x=49+1 \\ 10x=50 \\ x=(50)/(10) \\ \\ x=5 \end{gathered}`

The answer is x=5
