Find the products of the following and find the value of the product by taking * = -3, y = 2 (6) 3x and y + 13x (a) 3xły, - xy2 and -xy (c) 5xy and (x + y) 5. Simplify: 2xy (x - 4) + 5y and find its value for (i) x = 2, y = -1 (i) = = x 1; 6. (a) Add : x (x + y); y (y + z); z(z + x) (b) Add : 3m (1 - m - n) and 2n (m-1-1) (c) Subtract : 2x (x - 3y + 4z) from x(7x - y + 9z) (d) Subtract: (a - b + c) - 2- a + b -c) from 5 (a + 2b - )​

Step-by-step explanation:

13x (a) 3xły, - xy2 and -xy (c) 5xy and (x + y) 5. Simplify: 2xy (x - 4) + 5y and find its value for (i) x = 2, y = -1 (i) = = x 1; 6. (a) Add : x (x + y); y (y + z); z(z + x) (b) Add : 3m (1 - m - n) and 2n (m-1-1) (c) Subtract : 2x (x - 3y + 4z) from x(7x - y + 9z) (d) Subtract: (a - b + c) - 2- a + b -c) from 5 (a + 2b - )
