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
Answer:
n = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
[tex]\frac{7}{9}[/tex] + n = 3n + [tex]\frac{1}{9}[/tex]
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 )
[tex]\frac{6}{18}[/tex] = n , that is
n = [tex]\frac{1}{3}[/tex]
