-5 = b -2/3 b= __ Please help!

Inga [223]

Answer:

b = - $4\frac{1}{3}$

b = - $\frac{13}{3}$

Step-by-step explanation:

-5 = b - $\frac{2}{3}$

Add $\frac{2}{3}$ to both sides of the equation to get rid of the "- $\frac{2}{3}$ " on the right side.

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

Simplify

- $4\frac{1}{3}$ = b

b = - $4\frac{1}{3}$

b = - $\frac{13}{3}$
