Full solution

Q. Solve for

r

.

\newline

\text{–}(r - 4) = \text{–}5

\newline

r =

\underline{\hspace{2em}}

Divide by $-1$ : Write the expression after dividing both sides by $-1$ to remove the negative sign. $\newline$ Divide both sides by $–1$ . $\newline$ $–(r − 4)/–1 = –5/–1$ $\newline$ $r - 4 = 5$
Add $4$ : Add $4$ to both sides to isolate the variable $r$ . $\newline$ $r - 4 + 4 = 5 + 4$ $\newline$ $r = 5 + 4$
Calculate sum: Calculate the sum to find the value of $r$ . $r = 9$
