Help please!

I've been stuck on this problem...
x+y=5000

0.03x+0.02y=186
0.03x+0.02(5000-x)=186
0.03x+100-0.02x=186
0.01+100=186
0.01x=86
x=8600 Then this number does not make sense because its more then the total.

I also tried to flip the x and y but i still didn't get the correct answer.

Thank you!

The interest rates are 3% and 5%. I think you used an interest rate of 2%. You have the right ideas for the set up and solving!

You have the incorrect interest rate for y. It should be 0.03x + 0.05y = 186

Where am I going wrong????
x+y=5000 y=5000-x

            0.03x+0.05y=186

0.03x+0.05(5000-x)=186
0.03x+250-0.05x=186
-0.02x=-64
x=3200

                                  y=5000-3200=1800

1800+3200=5000
5000=5000

I don't know how to get the amount from interest in each account? Where am I going wrong? Just a hint cause its really driving me crazy!
Thanks Simon

That's right
now you need to calculate the interest of each account.
1800 * 0.05 = 90
3200 * 0.03 = 96
90 + 96 = 186

hope this helps

note: the answers are "3200" and "1800"
