To solve the system of equation
Answer to Problem 6.3.5P
Explanation of Solution
Given information:
Calculation:
Let’s assume equations be (1) and (2) respectively
To solve equations by elimination, the given equations are either added or subtracted to get an equation in only one variable.
Let’s eliminate variable a here. To eliminate a variable, the coefficients of the variable must be same in both the equations.
Here, coefficients of a is same. Now add equations.
Solving,
So,
Put value of b in (1)
Solving,
Dividing by -2,
Hence,
