Question

M+-2/3=-1/3 what is m?

Answer 1

$m + - \frac{2}{3} = - \frac{1}{3} \\ \\ m - \frac{2}{3} = - \frac{1}{3} \ / \ simplify \\ \\ m = - \frac{1}{3} + \frac{2}{3} \ / \ add \ \frac{2}{3} \ to \ each \ side \\ \\ m = \frac{1}{3} \ / \ simplify \\ \\ Answer: \fbox {m = 1/3} \ or \ \fbox {m = 0.3333}$

Answer 2

M+ -2/3= -1/3
⇒ M+ (-2/3)= -1/3
⇒ M= -1/3+ 2/3
⇒ M= 1/3

Final answer: M= 1/3~
