Q. Given

h(x)=-x-3

, solve for

x

when

h(x)=7

.

\newline

Answer:

Given function and target value: We are given the function $h(x) = -x - 3$ and we need to find the value of $x$ when $h(x) = 7$ . $\newline$ Set $h(x)$ equal to $7$ . $\newline$ $- x - 3 = 7$
Set equation equal to $7$ : Add $3$ to both sides of the equation to isolate the term with $x$ on one side. $\newline$ $- x - 3 + 3 = 7 + 3$ $\newline$ $- x = 10$
Isolate $x$ term: Multiply both sides by $-1$ to solve for $x$ . $\newline$ $-1 \times (-x) = -1 \times 10$ $\newline$ $x = -10$
