Find A and B. Ax-2y=4 A*-1 - 2*3 = 4 -A - 6 = 4 -A = 10 A = -10 -------------- 5x+By=-1 Find B the same way. Answer by stanbon(60771)   (Show Source): You can put this solution on YOUR website!The solution to the following system is (-1,3). Find A and B. Ax-2y=4 5x+By=-1 --- Substitute to get: A(-1) - 2(3) = 4 5(-1) + B(3) = -1 ----------------------- -A - 6 = 4 -5 + 3B = -1 ------------------- A = -10 B = 4/3 ============= Cheers, Stan H. =============
