Respuesta :
Get all the q terms to one side of the equation and isolate them.
Add 18 to both sides and subtract qr from both sides.
6q-qr=s+18
Factor out a q on the left side.
q(6-r)=s+18
Divide by (6-r) on both sides to solve for q.
q=(s+18)/(6-r)
Add 18 to both sides and subtract qr from both sides.
6q-qr=s+18
Factor out a q on the left side.
q(6-r)=s+18
Divide by (6-r) on both sides to solve for q.
q=(s+18)/(6-r)
