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.
The teacher has $36 to spend on the granola bars.
The equation 9(7 - x) = 36 represents a situation where she spends all $36.
9(7 - x) = 36
On simplifying, then we have
63 - 9x = 36
9x = 63 - 36
9x = 27
x = 3
