Y = x-1
Given x = 5
y =

When x=5, y=4

Step-by-step explanation:

Whenever you have to solve these kinds of equations, all you have to do is substitute what you already have into it.

The equation you've been given is:

y = x - 1

They want you to find what y is, when x = 5

So substitute in x=5:

y = 5 - 1

y=4
