To state: The solutions for the system of equation.
The resultant solution is
Given information:
The given system equations is:
Explanation:
Write the original system equations:
Let’s number the equation,
Multiply equation (2) by 2,
Add equation (1) and (4) to eliminate variable y ,
Number the resultant equation,
Multiply equation (3) by -2,
Add equation (1) and (6) to eliminate variable y ,
Number the resultant equation,
Now multiply equation (5) by 7 and equation (7) by -5,
Add equation (8) and (9) to eliminate variable x ,
Now find the value of variable y by substituting the value of x in equation (7) and simplify,
Now find the value of variable y by substituting the values of y and x in equation (1) and simplify,
Therefore, the solution for the given system of equation is
