Answer to Problem 3.2.6EP
Explanation of Solution
Given information:
The given equations are:
In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
Now multiplying equation 2 by 2 to make the coefficients of
Now as we can see coefficient of
Now putting value of
