Choose a variable to eliminate and two equations to work with.
There are many possibilities.
We will use the first and third equations and eliminate x in the example.
Multiply the third equation by −1 then add it to the first.
Choose a different pair of equations and eliminate the same variable.
Here, we use the second and third equations.
Multiply the third equation by −2 then add it to the second.
Now combine the two result equations.
Solve for z and substitute to find the other values.
Check your result in each equation.
