3x-y=3;9x-3y=9 by sublimation method |
|
Answer» 3x-y=3 -----(1) 9x-3y=9------(2) x= 3+y / 3 9 ( 3+y / 3) = 9 27+9y /3 = 9 27 +9y = 9*3 9y = 27-27 9y =0 y=0/9 y=0 (put value of y in 1st equation) 3x-y=3 3x-0=3 3x=3 x=3/3 x = 1 (1,0) therefore, value of x and y by substitution method is 1 and 0 3x-y=3; 9x-3y=9; 3(3x-y=3) 9x-3y=9, 9x-3y=9/3y+3y=18, 6y=18; y=18/6=9/3 =3; 3x-y=3; 3x=3+3=6; x=6/3=2 X= 1 ,Y= 0 is the correct answer of the given question x=1 AND y=0 hope you like it |
