A + B = 40 ------------- EQ (1)
A – B = 60 ------------- EQ(2)
+
------------------------------------------------------
2A =100
A = 100/2
A= 50
SUBSTITUTE A=50 IN EQ (1) OR EQ(2)
A + B = 40
50 + B =40
B=40-50=-10
THEN (2A-3B)/A+B = [2(50)-3(-10)]/50-10=100+30/40=130/40=3.25
mico:
how 2a= 100
we have to add EEQ(1) and EQ(2), i.e.,A+B+A-B=60+40
expected answer is 7/6 . ?
