To solve the system of equations
Answer to Problem 6.3.4P
Explanation of Solution
Given information:
Calculation:
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 x here. To eliminate a variable, the coefficients of the variable must be same in both the equations.
Here, coefficient of y is same. Now add the equations
Solving equation,
This gives us,
Put value of x in (1)
Solving,
Dividing by -2,
Hence,
