To solve the system
Answer to Problem 6.4STP
Explanation of Solution
Given information:
Calculation:
Assume equation 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 y here. To eliminate a variable, the coefficients of the variable must be same in both the equations.
Here, coefficients of y is same, now subtract (1) and (2)
Solving,
Dividing equation by -4
Put value of x in (1)
Solving,
so,
Dividing equation by -2,
Hence,
