Q. Evaluate the expression for

b = 1

.

\newline

Write your answer in simplest form.

\newline

\frac{b - 6}{-b + 7} =

__

Identify Expression: Identify the expression after substituting $b = 1$ $\newline$ Substitute $1$ for $b$ in $\frac{(b - 6)}{(-b + 7)}$ . $\newline$ $\frac{(1 - 6)}{(-1 + 7)}$
Substitute for $b$ : Evaluate $(1) - 6$ $1 - 6 = -5$ Numerator: $-5$
Evaluate Numerator: Evaluate $-1 + 7$ $-1 + 7 = 6$ Denominator: $6$
Evaluate Denominator: $-\frac{5}{6}$ $\newline$ The fraction is already in its simplest form. $\newline$ Final expression: $-\frac{5}{6}$
