Answer:
[tex]y=(p+q)(-4y+8)[/tex]
Step-by-step explanation:
[tex]\text{Solution:}[/tex]
[tex]\text{By reverse distribution,}\\[/tex]
[tex]py+qy=-4y+8\\\text{or, }y(p+q)=-4y+8[/tex]
[tex]\text{Dividing by }(p+q)\text{ on both sides,}[/tex]
[tex]\dfrac{y(p+q)}{(p+q)}=(p+q)(-4y+8)\\\\\text{or, }y=(p+q)(-4y+8)[/tex]
