3Select the correct answerHow many solutions for x does the following equation have?2(x + 4) - 1 = 2x + 7OA. 7B.c.infiniteOD.1ResetResetNext

Answer 1

the initial equation is:

`4(8-x)=8`

So we can solve the equation to find the possible solution of the equation so:

`\begin{gathered} 8-x=(8)/(4)=2 \\ 8-2=x \\ 6=x \end{gathered}`

So the only possible solution of the equation is 6, so solution is option C
