Explanation:
Given the equation :
![0.5s+1=7+4.5s](https://img.qammunity.org/2019/formulas/mathematics/middle-school/b99undfpnd3rjcrqpr8lv4mkdlqtmlw6ji.png)
the first step is to put all the terms with the variable we want to solve for on one side of the equation, in this case I will put all the terms with
on the right side, and all the independent terms on the left side.
![1-7=4.5s-0.5s](https://img.qammunity.org/2019/formulas/mathematics/middle-school/n7b1oqo61zdon296xp1k185po0dcjadl74.png)
Solving for
we have the following:
![-6=4s](https://img.qammunity.org/2019/formulas/mathematics/middle-school/mjgv2rxprpmzp2n4as3bcz0qyjsqku8zdw.png)
![(-6)/(4) =s](https://img.qammunity.org/2019/formulas/mathematics/middle-school/d2l4v71rljw0qtx6mdlr6iocwjd7uv5slx.png)
![-1.5 =s](https://img.qammunity.org/2019/formulas/mathematics/middle-school/wxmxmxf2yz2oyn0kxdc0gq6txd33aw1sok.png)
the answer is:
