How do you solve the following system?: #8x +6y =9 , - 5x -7y = -2#
With some arrangement.
Expand the first equation with term 5
Expand the second equation with 8.
Now you have:
Now sum these up:
Now you can find x using the first or second equation:
You can solve this system by using Elimination method.
You can eliminate either
I will eliminate
So multiplying eq.(i) by
Adding eq (iii) and (iv), you will get
