Question
How to solve this
-95A+20B=40
-20A-95B=100?

Answer
First, divide each equation by 5 to get -19A+4B= 8 and -4A-19B =20.
Multiply the first equation by 19 to get -361A+76B = 15
Multiply the second equation by 4 to get  -16A-76B = 80
Add those two to get -377A = 232 so A = -0.61538 and then B = -0.923
