Linear Equations in Two Variables Exercise 3 Q1. Draw the graph of each of the following linear equation in two variables: (i) x + y = 4 (ii) x – y = 2 (iii) y = 3x (iv) 3 = 2x + y Sol. (i) The given equation is x + y = 4 y = 4 – x …………….equation (1) Now ‚ putting the value x = 0 in equation (1) y = 4 – 0 = 4. So the solution is (0‚ 4) Putting the value x = 1 in equation (1) y = 4 – 1 = 3. So the solution is (1‚ 3) Putting the value x = 2 in equation (1) y = 4 – 2 = 2. So the solution

Answers are hi-lighted yellow. Company A’s nationally advertised brand is Brand X. Contribution to profit with Brand X is $40 per case. Company A’s re-proportioned formula is sold under a private label Brand Y. Contribution to profit with Brand Y is $30 per case. Company A’s objective is to maximize the total contribution to profit. Three constraints limit the number of cases of Brand X and Brand Y that can be produced. Constraint 1: The available units of nutrient C (n) is 30. Constraint 2:
