Question

What is the value of y in the equation y + 9 = 13?

Answer 1

The given equation is:

`y+9=13`

Recall the Subtraction Property of Equality:

Hence, to find the value of y, subtract 9 from both sides of the equation:

`\begin{gathered} y+9-9=13-9 \\ \Rightarrow y+0=4 \\ \Rightarrow y=4 \end{gathered}`The value of y is 4.
