In other words, we are looking for the ordered triple \((x,y,z)\) that makes all three equations true. These are called the solutions of the system of three linear equations with three variables. So the way that you would proceed to solve three equations with three unknowns is you would try to eliminate variables one by one. And so first we could try to eliminate the x variables. And we could do that, we can essentially create two equations with two unknowns. The two unknowns will be y and z.
