Answer:
[tex]y=-8/[p+q+4][/tex]
Step-by-step explanation:
we have
[tex]py+qy=-4y+(-8)[/tex]
[tex]py+qy=-4y-8[/tex]
Solve for y
That means ----> isolate the variable y
Adds 4y both sides
[tex]py+qy+4y=-4y-8+4y[/tex]
[tex]py+qy+4y=-8[/tex]
Factor the variable y in the let side
[tex]y[p+q+4]=-8[/tex]
Divide by (p+q+4) both sides
[tex]y=-8/[p+q+4][/tex]
