Solution

Solution is wrong:

How to solve the equation :

1) you can use matrix

2) Now a days calculators have the functionality to solve equation with three unknown.

3)

Step 1: first take any two equation and terminate a variable by addition or subtraction.

Step 2: Then take the third equation with any of the above equation and again terminate the same variable you terminate in step 1 by simple addition or subtraction.

Step 3: Now you will be left with two equations with two unknowns. Which can be solved easily thus solving for two variables

Step 4: third unknown can be obtained by substituting the values from step 3 to any of equation above.
