Answer:
The correct answer is D
Step-by-step explanation:
1/2bh
8x4=32/2=16
<u><em>I am doing this problem assuming that you mean to solve for m and n as x and y do not exist in this system of equations.</em></u>
<u><em /></u>
-4m+2n=6
-4m+n=8
We can see that the coefficient of x for both equations are -4; therefore, elimination with subtraction is possible.
<u>First equation - second equation</u>
n=-2
<u>Then substitude back in to solve for m</u>
-4m+(-2)=8
4m=10
m=5/2
Therefore the answer is
n= - 2
m= 5/2
