To solve the system of equations
Answer to Problem 6.3.7P
Explanation of Solution
Given information:
Calculation:
Let’s assume the 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 x here. To eliminate a variable, the coefficients of the variable must be same in both the equations.
Here, coefficient of x is same. Now, add the equations
Solving,
Adding terms,
So,
Put y in equation (1)
Solving the equation,
So,
Multiplying both sides by 2,
Hence,
