solve for x and y:2x+3y=94x+6y=18 |
|
Answer» 2x + 3y = 9......... (i)4x + 6y = 18 .... (ii)On multiplying equation (1) with 2, we get2(2x + 3y) = 2(9)⇒ 4x + 6y = 18 .... (iii)Here, both the equation (ii) and (iii) 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. Y=5/3; x=6{substition method} |
