Sagot :
1.) .07x + .11y = 760
2.) x + y=8000
we can solve the second equation for either x or y
y= 8000 - x
or
x=8000 - y
plug 1 of those in to equation 1 (I'll use y=8000 -x)
.07x + .11(8000 -x) = 760
.07x + 880 - .11x = 760
-.04x +880 = 760
-.04x = -120
x=3000
So 3000 is invested in 7%
5000 is invested in 11%
Check
(3000 x .07) + (5000 x .11) = 720
210 + 550 = 760
Success!
