The answer is no.4 i.e. infinitely many solutions
Step-by-step explanation:
Given the equation ![4s+8=3+5+4s](/tpl/images/0377/3321/8ee1c.png)
When we solve it
![4s+8=8+4s](/tpl/images/0377/3321/220fb.png)
Since the terms on the left hand side is the same on the right hand side
∴ Putting any value of s will satisfy the equation
For ex : 3
![4\times 3+8\\=8+4\times 3](/tpl/images/0377/3321/ffe31.png)
Similarly the equation will be satisfied with infinitely many values
