ax+by=c
dx+ey= f
What would be the general solution to this systems of linear equations using the variables..so what would x and y be?
Please help with step by step instructions! thanks!

Try using matrices (we'll call them mA, mB, and mC):
[a b] + [x] =[c]
[d e] + [y] =[f]
Multiply mC by the inverse of mA to get the answers.
To get mA:
[e -b]
[-d a]
And multiply by the determinate, which is 1/(ad-bc)
For simplicity's sake, we're going to multiply the above matrix by the det and call it
[eD -bD]
[-dD aD]
Now multiply this by the third matrix, mC:
eD*c+(-bD*f)=x
-dD*c+aD*f=y
Points would be much appreciated cause this took a hell of a long time to type up ;)
