Answer:

[tex]x=-3\ and\ x=2[/tex]

Step-by-step explanation:

we have

[tex]\frac{2}{5}+\frac{3}{5x}=\frac{x+5}{10}[/tex]

Simplify-----> Multiply by [tex]10x[/tex] both sides

[tex]10x*\frac{2}{5}+10x*\frac{3}{5x}=10x*\frac{x+5}{10}[/tex]

[tex]4x+6=x^{2}+5x[/tex]

[tex]x^{2}+5x-4x-6=0[/tex]

[tex]x^{2}+x-6=0[/tex]

Using a graphing tool-----> to resolve the quadratic equation

see the attached figure

The solutions are

[tex]x=-3\ and\ x=2[/tex]
