Answer:
y=8/(p+q+4)
Step-by-step explanation:
py+qy=-4y+8
Collect all terms containing y together
Py+qy+4y=8
Factor out y
y(p+q+4)=8
Divide both sides by (p+q+4)
y(p+q+4)/(p+q+4)=8/(p+q+4)
y=8/(p+q+4)
If you mean just any fraction in the world that isn't equivalent to 1/3, then 5/6 7/9 and 2/10 would work
Hope this helps! Good Luck!
