2·14=28
28-3=25
25÷5=5

Answer:

[tex]n=\frac{28}{10}=2.8[/tex]

Step-by-step explanation:

We have the expression [tex]2n-\frac{3}{5}=5[/tex] we have to find the value of n, then the first step is add [tex]\frac{3}{5}[/tex] in both sides of the equation:

[tex]2n-\frac{3}{5}=5\\\\2n-\frac{3}{5}+\frac{3}{5}=5+\frac{3}{5}\\\\2n=5+\frac{3}{5}\\\\2n=\frac{5.5+3}{5} \\\\2n=\frac{28}{5}[/tex]

Now we have to divide both sides of the equation in 2:

[tex]2n=\frac{28}{5}\\\\\frac{2n}{2}=\frac{\frac{28}{5}}{2}\\\\n=\frac{28}{2.5}\\\\n=\frac{28}{10}=2.8[/tex]

Then n=2.8
