The pair of equation X+y=1 and X+y=-5 has |
|
Answer» X+y=1X+y-1=0...... Eq.1X+y=-5X+y+5=0.........Eq.2From eq.1 and eq.2 we have:a1=X b1=y. c1=-1a1=X. b1=y. c2=5a1/a2 =X/X =1b1/b2=y/y=1c1/c2=-1/5Therefore the following equation has no solution as a1/a2=b1/b2but not equal to c1/c2 Well find value of x by solving eq 1 and than use substitution method and put the value of x into eq 2 x+y=-5 than u get the value of y after that put the value of y into the eq 3 x=1-y u get value of x No solution X+y=1 |
