A- 2b = 2 one of the 2 "A" most be negative so they can cancer each other
-a- b = 6 after the "A" cancel each other add the -2b with -b = -3b, then add 2
-------------- and 6
-3b=8 then you have to divide 8 by -3 = -2.6 -2.6 its b... now you have to solve for b step 1. a -2b = 2 step 2. a -2(-2.6)=2 step 3 a -5.3 = 2 then subtract -5.3 with 2 so that going to be 2 + 5.3 =7.3 then divide by a
final answer (-2.5,-7.3)
sorry its kinda hard to explained here, i hope you get the point :)
