I need help with this  I know I need to multiple by 100 to get ride of the decimals
solve by the elimination method 0.5x0.2y=4 0.5x+0.3y=7/17
3x2y=40 5x+3y=70/17
Then I am lost  can some help me?

Best ResponseYou've already chosen the best response.0after multiplying with 10, the first equation should be: \[5x  2y = 40\] probably just a typo, tho...

Best ResponseYou've already chosen the best response.0that's correct (altough unnessesary). But this was a multiplication with 10! 0.3x multiplied with 100 would be 30x !

Best ResponseYou've already chosen the best response.0Now  'elimination method' means, multiply one equation with some factor, so that, after adding both of the equations together either x or y is eliminated... Can you come up with something on your own?

Best ResponseYou've already chosen the best response.0You are right I went back to notes  for elimination method it multiplication of 10 not 100
