Q. If

-k+78=98-20

, then what is the value of

k

?

Write Equation: Write down the given equation. $-k + 78 = 98 - 20$
Simplify Equation: Simplify both sides of the equation. $\newline$ On the right side, subtract $20$ from $98$ . $\newline$ $98 - 20 = 78$ $\newline$ Now the equation is: $\newline$ $-k + 78 = 78$
Isolate Variable: Since both sides of the equation now have the same number, $78$ , we can subtract $78$ from both sides to isolate the variable $k$ . $\newline$ $-k + 78 - 78 = 78 - 78$ $\newline$ This simplifies to: $\newline$ $-k = 0$
Get Rid of Negative Sign: To find the value of $k$ , we need to get rid of the negative sign in front of $k$ . $\newline$ Multiply both sides by $-1$ to get $k$ by itself. $\newline$ $-k \cdot -1 = 0 \cdot -1$ $\newline$ This simplifies to: $\newline$ $k = 0$
