Question 205901
I need help making a system of equations based on a word problem, this is the problem: Helen invested a total of $1,000 in two simple interest accounts. One account paid 4% annual interest; the other paid 6% annual interest. The total amount of interest earned was $58. Write and solve a system of equations to find the amount invested in each account.
<pre><font size = 4 color = "indigo"><b>

100% of $X plus 100% of $Y equals $1000
  4% of $X plus   6% of $Y equals   $58

{{{system(X+Y=1000,.04X+.06Y = 58)}}}

To solve that clear the second equation of decimals by
multiplying through by 100:

{{{system(X+Y=1000,4X+6Y =5800)}}}

Solve that by either substitution or by elimination:

X = $100 at 4% and $900 at 6%
