Question

Step 1

We have been given a system of linear equation in 3 variables that we need to solve.

Step 2

First we will make the coefficients of variable y equal in all the equations and then eliminate the variable y by considering two equations at a time. Upon doing so, we get a system of linear equations in 2 variables as shown below:

Step 3

Now we will solve this sytem in variable x and z first. And then we can easily find the value of...
