<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
I hope this helped and if you have any questions please ask.
-0,5=-1/2
-1/2•(-2)=1
The answer is 1
Yes. Simply, if you have $.6o, or 60 cents and you give half to someone else, you both have 30 cents or 0.3.
1. (3,-2)
2. (-2,2)
3. (1/3,2/3)
4. (13/7, 40/7)
