Step-by-step explanation:

The equation is given below as


4(2s-1)=7s+12

Step1:

Expand the parenthesis


\begin{gathered} 4(2s-1)=7s+12 \\ 8s-4=7s+12 \end{gathered}

Step 2:

Collect the similar terms, we will have


\begin{gathered} 8s-4=7s+12 \\ using\text{ the cross over technique} \\ 7s\text{ moves to the left hand side and takes the negative sigh\lparen-7s\rparen} \\ -4\text{ moves to the right hand side and becomes +4} \\ 8s-7x=12+4 \\ s=16 \end{gathered}

Hence,

The value of s will be


\Rightarrow s=16
