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 =
