Answer:

$\frac{22}{3}$ = b

7 $\frac{1}{3}$ = b

(they are the same value, just different ways of writing it)

Step-by-step explanation:

4 = - $\frac{2}{3}$ (5) + b

simplify

4 = - $\frac{10}{3}$ + b

now use inverse operations

4 = - $\frac{10}{3}$ + b

+ $\frac{10}{3}$ + $\frac{10}{3}$

$\frac{22}{3}$ = b
