multiply first equation by 2
-30r+24s=48
+30r-24s=48
hmm, if I add those, I get 0 = 96. a problem all right
try multiplying the second one by -1 then look
-30r+24s=48
-30r+24s=-48
that is two parallel lines with the same slope but they never cross (different intercepts). There are no solutions.
Soe using the eliminatin method.Show work.State if it has infinite solutions or no solutions...-15r+12s=24,30r-24s=48
