Answer :
The variable in the equation is represented by y, to solve the equation, you must find the value of variable y that makes the equation true, and 1 is a solution to the equation because it satisfies the equation and is a true statement.
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 linear equation is given below.
y + 4 = 5
Then the value of y will be given as
y + 4 = 5
y = 5 - 4
y = 1
