Answer:
Those system of equations are called the system of linear equations with multiple variables.
Step-by-step explanation:
Here it is given a system equations as
x = 5 ....... (1)
y = 6 ........... (2) and
- x - y + z = 0 ........ (3)
Those systems of equations are called the system of linear equations with multiple variables.
Those are linear equations as the maximum power of the variables is 1.
We can solve those equations with simple algebra.
Here, x = 5, y = 6 and z = x + y = 5 + 6 = 11 (Answer)
