Step-by-step explanation

Given the equation


2(x-1)+4x=14

We can find the equivalent equations below.

Number 1


\begin{gathered} 2(x-1)+4x=14 \\ 2x-2+4x=14 \end{gathered}

Number 2


\begin{gathered} 2(x-1)+4x=14 \\ 2x-2+4x=14 \\ 2(x-1+2x)=14 \\ x-1+2x=7 \end{gathered}

Number 3


\begin{gathered} 2(x-1)+4x=14 \\ 2x-2+4x=14 \\ 6x-2=14 \end{gathered}

Answer:


\begin{gathered} \Rightarrow2x-2+4x=14 \\ \Rightarrow x-1+2x=7 \\ \Rightarrow6x-2=14 \end{gathered}
