Answer:
x = 
Step-by-step explanation:
<u>To solve quadratic systems,we always substitute one variable in terms if the other and then solve the equation.</u>
x + 2y = 6 ---------------(1)
y - 5 =
---------------(2)
y =
+ 5 ---------------(3)
Substitute (3) in (1) ,
x + 2(
+ 5 ) = 6
=
x + 2(
+ 5 ) = 6
--------------(4)
The roots of the quadratic equation
is
x =
-----------(5)
According to equation (5),solution of (4) is
x = 
x = 
x =
