7x-15y=2.........1 7(X+2y)=3*7..........2 From eq.1 &eq.2 7x - 15y = 2 7x +14y = 21 ...↑-....↑-........↑-........... 0 -29y = -19 Therefore; y = -19/-29 Y = 19/29???????? Putting the value of "Y" in eq.2 X + 2y = 3 X + 2(19/29)=3 X +2*19/29 = 3 X = 3 - 38/29 X = 49/29??????? Hence; X = 49/29 and Y = 19/29....
