Q. Solve for

k

.

\newline

k + 2 = 15

\newline

k =

_____

Subtract $2$ from both sides: $k + 2 = 15$ $\newline$ To solve for $k$ , we need to isolate $k$ on one side of the equation. $\newline$ We can do this by subtracting $2$ from both sides of the equation. $\newline$ $k + 2 - 2 = 15 - 2$
Find the value of $k$ : $k = 13$ $\newline$ After subtracting $2$ from both sides, we find that $k$ equals $13$ . $\newline$ This is the value of $k$ that satisfies the equation.
