Answer to Problem 10MRE
Explanation of Solution
Given:
Equations:
Concept used:
The following steps are to be followed to find the unique solution to the system of equations:
- Choose an equation to find same coefficient in the equations.
- If the system of equations does not have same coefficient, multiply either one or both the equations with a common factor.
- Add or subtract the equations to find the value of one of the variables.
- Substitute the variable found in any of the equations and find the other which is the unique solution.
Calculation:
Consider the given equations.
Multiply
