Answer:
[tex]15n=10\\\\n=\dfrac{10}{15}\\\\n=\dfrac{2}{3}[/tex]
Step-by-step explanation:
We need to find out of 4 options which equation has a solution of 2/3 for n.
Equation (1).
[tex]n-1=\dfrac{1}{3}\\\\n=\dfrac{1}{3}+1\\\\n=\dfrac{4}{3}[/tex]
Equation (2).
[tex]16n=24\\\\n=\dfrac{24}{16}\\\\n=\dfrac{3}{2}[/tex]
Equation (3).
[tex]15n=10\\\\n=\dfrac{10}{15}\\\\n=\dfrac{2}{3}[/tex]
Equation (4).
[tex]1\dfrac{1}{3}+n=3\\\\n=3-\dfrac{4}{3}\\\\n=\dfrac{5}{3}[/tex]
So, equation (3) has a value of n as 2/3. Hence, the correct option is (3).
