Answer 1

Answer:

The output is 5

Step-by-step explanation:

we have

$y=2x-1$

In this linear equation the input is the variable x and the output is the variable y

so

If the input is 3

That means ------> x=3

substitute the value of x in the equation and find the value of y (output)

$y=2(3)-1=5$
