Look the equation below.

If x=4, what is the value of y?
y=(x-1)+13
Explain your thinking.

plug in 4 for x. y=16

y=(x-1)+13

Substitute 4 for x

y = (4 - 1) + 13

y = ?

To find the value of y when x=4, you can substitute the value of x into the equation and simplify.

Start with the given equation:
y = (x-1) + 13

Substitute x=4 into the equation:
y = (4-1) + 13

Simplify:
y = 3 + 13

Add the numbers:
y = 16

Therefore, when x=4, the value of y is 16.
