Answer:
The equations:
the value for x and y:
Step-by-step explanation:
invest amount = 12900
let x = amount put into the first account
let y = amount put into the second account
we know the sum of of both is 12900, thus
We also know the sum of their annual interest rate is 1103
Thus the equations needed are
and
To find the values for x and you know have all equations you need
we need to get this equation to a single variable
we can do this using x or y, lets use x
we know
, so
lets plug into
1161 - .09y + .08y = 1103
-.01y = -58
y = 5800
we can get x from this equation from above
