{:[f(t)=-2t+5],[f(◻)=13]:}

Write function and value: Write down the function and the value for f(t) that we are looking for. We are given f(t) = -2t + 5 and we want to find the value of 't' when f(t) = 13.Set function equal to 13: Set the function equal to 13 and solve for 't'. So, we have -2t + 5 = 13.Isolate terms with 't': Subtract 5 from both sides of the equation to isolate terms with 't'. -2t + 5 - 5 = 13 - 5 This simplifies to -2t = 8.Solve for 't': Divide both sides of the equation by -2 to solve for 't'. -2t / -2 = 8 / -2 This gives us t = -4.

\begin{array}{l}f(t)=-2 t+5 \\ f(\square)=13\end{array}

Write function and value: Write down the function and the value for $f(t)$ that we are looking for. $\newline$ We are given $f(t) = -2t + 5$ and we want to find the value of ' $t$ ' when $f(t) = 13$ .
Set function equal to $13$ : Set the function equal to $13$ and solve for $t$ . $\newline$ So, we have $-2t + 5 = 13$ .
Isolate terms with 't': Subtract $5$ from both sides of the equation to isolate terms with 't'. $\newline$ $-2t + 5 - 5 = 13 - 5$ $\newline$ This simplifies to $-2t = 8$ .
Solve for 't': Divide both sides of the equation by $-2$ to solve for 't'. $\newline$ $-2t / -2 = 8 / -2$ $\newline$ This gives us $t = -4$ .
