R+D=12 (1)
2.50R+1.75D=24.75 (2)
Now you are told to use elimination, which is not the best way in my oppinion but to do this you must multiply the first one by something either 1.75 or 2.5.
I'll mult it by 2.5
2.5R+2.5D=30 (1b)
2.50R+1.75D=24.75 (2)
No subtract (2) from (1)
2.5D-1.75D=30-24.75
can you finish it?
