(ii) pencils and pens together cost ` , whereas pencils and pens together cost ` . Find the cost of one pencil and that of one pen. . On comparing the ratios , c , find out whether the lines representing the following pairs of linear equations intersect at a point, are parallel or coincident: (i) x – y + = (ii) x + y + = x + y – = x + y + = (iii) x – y + = x – y + = .
On comparing the ratios , c , find out whether the following pair of linear equations are consistent, or inconsistent. (i) x + y = ; x – y = (ii) x – y = ; x – y = (iii) ; x – y = (iv) x – y = ; – x + y = – (v) x ; x + y = . Which of the following pairs of linear equations are consistent/inconsistent? If consistent, obtain the solution graphically: (i) x + y = , x + y = (ii) x – y = , x – y = (iii) x + y – = , x – y – = (iv) x – y – = , x – y – = .
