Answer:
The solution x = 
Step-by-step explanation:
<u>Step 1</u>:-
Given 
we have to use formula 
=
Again by using formula 

so 
<u>step 2:</u>-


The solution of given problem is 
Y = -x + 4.....so sub in -x + 4 in for y in the other equation
x + 2y = -8
x + 2(-x + 4) = -8
x - 2x + 8 = -8
x - 2x = -8 - 8
-x = -16
x = 16
y = -x + 4
y = -16 + 4
y = - 12
one solution (16,-12)
