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 =
1) Solving in terms of h
V = lwh <em>Divide both sides by h</em>
<em />
So rearranging that equation we can find h, in terms of V, and l and w.
If we want to solve in terms of l, or w, we'll proceed similarly to isolate the variable we want on the left side, and the other terms on the right side.
