To calculate: The solution of the system of equation by elimination method.
The solution of system of equation is
Given Information:
The given system of equation is,
Concept Used:
In the elimination method, eliminate one variable from the result equation by using addition or subtraction method over the equation.
Calculation:
Consider the given system of equations,
Multiply the first equation by 2.
Add the equation (3) and the second given equation.
Solve the obtain result.
Now, find the value of y by substituting 3 for x in the equation
Hence, the required solution is
