Step-by-step explanation:

The question:
Find the value of "y" when "x" equals 17.
Given the equation:
- x + y = -27 ;
___________________
We plug in the given value: "17" ; for "x" ; and solve for "y" :
- 17 + y = -27 ;
_____________________
↔ y + (-17) = -27 ;
Rewrite as:
y − 17 = -27 ; {since: "adding a negative value" is the same
as "subtracting a positive value."}.
_____________________
Now, we add "17" to each side of the equation;
to isolate "y" on one side of the equation; and to solve for "y" :
y − 17 + 17 = -27 + 17 ;
to get:
y = - 10 .

Let
the amount of money invested at 9% and
the amount of money invested at 5%. The amount invested at 5% (
) is 1700$ less than the amount invested at 9% (
) it means:
(equation 1)
The investments produced 223$ which means:
. (equation 2)
We use the first equation to eliminate
from equation 2:
He invested 2200$ at 9% and 500$ at 5%.
