Final answer:
To solve [Q2.3], follow the steps for solving simultaneous equations. To solve [Q2.4] using linear programming, follow the steps for solving linear programming problems.
Step-by-step explanation:
To solve [Q2.3], we need more information about the problem or question being asked. However, in general, to solve a problem or equation using simultaneous equations, we follow these steps:
- Identify the unknowns in the problem and assign variables to them.
- Write down the equations that relate these unknowns.
- Manipulate the equations to eliminate one variable at a time.
- Solve the resulting equations to find the values of the unknowns.
- Check your solutions by substituting them back into the original equations.
To solve [Q2.4] using linear programming, we need the specific problem or question being asked. Linear programming is a mathematical technique used to optimize a linear objective function subject to linear constraints. The steps involved in solving a linear programming problem are:
- Define the decision variables and the objective function.
- Write down the constraints that limit the values of the decision variables.
- Graph the feasible region determined by the constraints.
- Identify the vertices of the feasible region.
- Evaluate the objective function at each vertex to find the optimal solution.
