hello sir,is there any easy way of solving 3 equations with 3 variables instead of elimination because elimination is too lengthy.

Expert Answer:

Usually, elimination is the most common way that people use to solve 3 variable equation.it involves multiplying one equation by a factor such that now either of the 3 variables has same coefficients as one another equation and then subtracting the 2 equations. 
 
Another way is that you can form the matrix representing the 3 equations and then use inverse and adjoint of the matrix to come up with the solution.
