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.
