Best ResponseYou've already chosen the best response.0multiply the top equation by 9 to cancel out the x's. Then you can solve for y. Once you have that, plug the y back in to find the x.

Best ResponseYou've already chosen the best response.0solve for x in the first equation(you could solve for any variable in either equation but this one looks like the best choice) 3x+24y = 24 3x = 2424y x = 8  8y now put this into equation2 for x 27x15y = 15 so 27(88y)  15y = 15 can you solve for y here @blkbutterfly13 ?
