SOLUTION: solve for x and y in 15x+10y=60 15x-9y=3

Question 1202909: solve for x and y in 15x+10y=60
15x-9y=3
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
15x + 10y = 60
15x - 9y = 3
subtract the second equation from the first to get 19y = 57 which yields y = 3.
solve for x in either equation to get x = 2.
your solution should be x = 2 and y = 3.
replace x and y in both equations to confirm the solution is correct.
first equation yields 15*2 + 10*3 = 60 which becomes 30 + 30 = 60 which is true.
second equation yields 15*2 - 9*3 = 30 - 27 = 3 which is also true.
solution is confirmeed to be good.
solution is x = 2 and y = 3.
