0.15x+0.05y=12

Answered by Finnigan
I would multiply through by 100 to clear the decimals first.

5x+25y=1100
15x+5y= 1200

You can either multiply the top clear through by -3 to get rid of the x's or do that with -5 on the bottom to make the y's drop out. Get rid of a variable letter so that only there is only one left standing by figuring out how you can wind up with opposites that add up to zero. Once you have solved for one thing, you can go back and substitute that back in to find the other thing (i.e. plug and chug)
