Answer:

n =
(1)/(3)

Explanation:


(7)/(9) + n = 3n +
(1)/(9)

Multiply through by 9 to clear the fractions

7 + 9n = 27n + 1 ( subtract 9n from both sides )

7 = 18n + 1 ( subtract 1 from both sides )

6 = 18n ( divide both sides by 18 )


(6)/(18) = n , that is

n =
(1)/(3)

subtract n from both sides

7/9 = 2n +1/9

subtract 1/9 from both sides

6/9 = 2n

divide both sides ÷2

n = 6/18 = 1/3
