The number of the desktop is 74 in the lab, then the number of the laptop in the lab is 84.
What is the linear system?
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
There are 156 laptops and desktop computers in the lab.
Let x be the number of the laptop and y be the number of the desktop.
x + y = 156 ...1
There are 8 more laptops than desktop computers.
x = y + 8
x - y = 8 ...2
Add equations 1 and 2, then we have
2x = 164
x = 82
Then the value of y will be
82 + y = 156
y = 74
