Evaluate the expression for x = 1. Write your answer in simplest form. x - 8/-x + 4 = ____

Identify Expression: Identify the expression after substituting x = 1 Substitute 1 for x in (x - 8)/(-x + 4). (1 - 8)/(-1 + 4)Substitute and Simplify: Evaluate 1 - 8 1 - 8 = -7 Numerator: -7Evaluate Numerator: Evaluate -1 + 4 -1 + 4 = 3 Denominator: 3Evaluate Denominator: -7/3 Write the fraction in simplest form. The fraction -7/3 is already in its simplest form because 7 and 3 are both prime numbers and do not have any common factors other than 1.

\frac{x - 8}{-x + 4} =

Identify Expression: Identify the expression after substituting $x = 1$ $\newline$ Substitute $1$ for $x$ in $(x - 8)/(-x + 4)$ . $\newline$ $(1 - 8)/(-1 + 4)$
Substitute and Simplify: Evaluate $1 - 8$ $\newline$ $1 - 8 = -7$ $\newline$ Numerator: $-7$
Evaluate Numerator: Evaluate $-1 + 4$ $\newline$ $-1 + 4 = 3$ $\newline$ Denominator: $3$
Evaluate Denominator: $-\frac{7}{3}$ $\newline$ Write the fraction in simplest form. $\newline$ The fraction $-\frac{7}{3}$ is already in its simplest form because $7$ and $3$ are both prime numbers and do not have any common factors other than $1$ .
