Question 997419
Assumed simple interest for both accounts.


Two quantities to invest, x and y.
{{{x+y=100000}}}.


Rates for interest are 3% and 6%, and investment will be 1 year.  Quantity of interest to earn
is  $4800.


{{{system(0.03*x+0.06*y=4800,x+y=100000)}}}


You did not show work or explain how your results were failing.  Did you find the same system
of equations?  Did you maybe make mistake in decimals?


Divide the members of the interest sum equation by 0.03 to simplify.
{{{system(x+2y=160000,x+y=100000)}}}
This system makes Elimination Method a good choice to begin solving it.



If done right,  {{{highlight(y=60000)}}} and you can find x easily.
