$f(x) = \frac{x + 7}{6 - x} \\ \frac{3}{2} = \frac{x + 7}{6 - x} \\ 3(6 - x) = 2(x + 7) \\ 18 - 3x = 2x + 14 \\ - 3x - 2x = 14 - 18 \\ - 5x = - 4 \\ \frac{ - 5x}{ - 5} = \frac{ - 4}{ - 5} \\ x = \frac{4}{5}$

Match each expression to its equivalent expression.

Galina-37 [17]

Answer:

white 1: black 3

white 2: black 1

white 3: black 2

Step-by-step explanation:

white 1: the denominator for the x values so it becomes 1-2=-1 which becomes -1/3x +1/4

White 2: same case as the first so we add 1+2=3 3/3=1 so that makes it x+1/4

white 3: there is only one x values that has 4 as the denominator therefore that makes the answer 3/4x+1/3
