Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
x = amount put into the 10% account
y = amount put into the 12% account

" there is $400 more in the account that pays 12% than there is in the other account" so

"The two accounts pay 10% and 12% in annual interest" and "the total interest for a year is $136" so we know

Multiply everything by 100 to get

and then plug in and solve for x

replace y with x+400

Subtract 4800 from both sides.

Divide both sides by 22.

Now use this to find y. Plug it into

replace x with 400

So $400 was put into the 10% account while $800 was put into the 12% account.
