Answer» (i) Given equation, 2x = -3 The above equation can be written in two variables as, 2x + 0y + 3 = 0 (ii) Given equation, y = 3 The above equation can be written in two variables as, 0x + y – 3 = 0 (iii) Given equation, 5x = 7/2 The above equation can be written in two variables as, 5x + 0y – 7/2 = 0 or 10x + 0y – 7 = 0 (iv) Given equation, y = 3/2 x The above equation can be written in two variables as, 2y = 3x 3x – 2y = 0 3x – 2y + 0 = 0 |
