Solve for x and y:x+2y-4=02x+4y-12=0 |
|
Answer» x + 2y - 4 = 0x + 2y = 4.......... (i)2x + 4y - 12 = 02x + 4y = 12x + 2y = 4 ......... (ii)Here, both the equation (i) and (ii) are same and we know that when both equations are exactly same there are infinitely many solutions and the value of x and y can\'t be predicted. There is no solution ,lines are parallel ?????? |
